Today, I found out my blood type is B. My parents are type A and type O. It's not genetically possible to be blood type B if your parents are A and O. This means I am either an adoptee, a mutant, or an illegitimate child. FML

it's like bioshock. genetic modifications are fun! :)

hmmmm maybe its genetics or something

First i think.
anyway, look at fawkes. he is a mutant but he still has an awesome level OVER 9000!

omg my bio teacher told us a story about something like this
im so sorry dude.

#4 - On 04/11/2009 at 8:52pm by RavensRule97

awwwww. Thats a hard way to find out. Unless they look like you...

#5 - On 04/11/2009 at 8:53pm by Ptvlover

It is possible to have B ,your ancestors might have had it .
It's nothing special , FYl :P !

#6 - On 04/11/2009 at 8:56pm by Tiramesu

It's not possible. His parent would be BO not OB. O is always just O, but O can come after A or B. Unless one of his parents is AB or BO, it's not posible. The possible genotypes for A type blood are AA and AO. O is just OO. Therefore, if one of your parents really has O blood, they're OO. If your other parent really is type A, then they're either AA or AO. That means it IS impossible to have type B blood. Ask your O parent whether they're really O or if they're BO.

#304 - On 07/15/2009 at 9:31am by saminess714

lol.

blood type BO positive... that would suck >_>

Im relly confused. I think it is possible. Who knows but you should just confront your 'rents.

#10 - On 04/11/2009 at 9:05pm by ohhhhshizzz

Actually, look up "Bombay Phenotype." If your dad has it, and your mom is I^Ai, it's possible.

#11 - On 04/11/2009 at 9:12pm by I_Should_Sleep

Actually, look up "Bombay Phenotype," it's possible.

#12 - On 04/11/2009 at 9:13pm by I_Should_Sleep

Well, that was assuming your dad was they type O, I guess it could be the other way too.

#13 - On 04/11/2009 at 9:15pm by I_Should_Sleep

maybe your parents cant bear children, but never told you


i mean, why bother


they just got some sperm from one of those clinics in the 70's

:)

#14 - On 04/11/2009 at 9:16pm by pwnrzero

no, its possible. we just learned about this.

#15 - On 04/11/2009 at 9:19pm by hockeygirl202

To people sayings its possible: It's not. If you don't understand genetics just take someone else's word for it.

#17 - On 04/11/2009 at 9:22pm by EmilyMarie

Unless it is a mutation, it can't be possible

O type is recessive, so one parent has to be OO

A and B are co dominant, which means the other parent is either AO or AA

FYL, man. FYL

#18 - On 04/11/2009 at 9:24pm by Icalasari

#4, actually, it's not possible. At all. Blood types are passed down from multiple generations. You're either one or the other, there is no "recessive gene", per say.
That sucks.

#19 - On 04/11/2009 at 9:24pm by imajinethat

maybe one of your parents is actually b? this almost happened to me, my mom thought my dad was o like her and so i couldnt be a, but she was just mistaken. (got a few laughs from the interns present though)

#20 - On 04/11/2009 at 9:26pm by chimmy

Like #10 said it is not genetically possible. Blood typing is a contribution from both your parents. At least ONE of the OP's parents has to be an AB or B-type for that to be possible.

Ask your parents, maybe there's a good story behind it?

#21 - On 04/11/2009 at 9:30pm by mini_munny

ohhh no- its not. nvm.

#22 - On 04/11/2009 at 9:30pm by hockeygirl202

There is another possibility. Your mother could have had a sperm donor. Perhaps not what you want to hear, but it is another option.

#28 - On 04/11/2009 at 9:36pm by eternalaphrodite

no... its actually possible
there wwas another same case years ago
its very strange but might not be what ya think :)

#29 - On 04/11/2009 at 9:36pm by janeaudghk

You sure one of your parents isn't B or AB?

#30 - On 04/11/2009 at 9:38pm by greatnt249

i'll go with mutant. makes life that much more exciting.

#31 - On 04/11/2009 at 9:38pm by hahahalol

lmao, I'm sorry, but thats horrible.

#32 - On 04/11/2009 at 9:42pm by bonestructure

LOL SURPRISE!!!

Just ask your mom about it. It can't be possible that you're adopted and they didn't tell you...well it shouldn't be possible. Maybe their that bad...but maybe you have another dad?

#33 - On 04/11/2009 at 9:43pm by Sens_fan9

aww thats suckss...
Maybe you should make sure that neither of your parents have type B..

#34 - On 04/11/2009 at 9:44pm by Sophalump

The Bombay phenotype is if you have an A and an O, though, with an AO (showing as an A) for their one side and a OO (showing as O).
If one person, for example, was AO and BB, it would show as AB.
O is sort of a canceling factor. A and B are dominant, and going to show. So if one parent was AB and the other would have to be OO, because A or B would show as the O, and the AB parent would be AB.

#35 - On 04/11/2009 at 9:45pm by imajinethat

Unless you're adopted, I'm sure your dad would also like to know how you got type B.

#36 - On 04/11/2009 at 9:46pm by cthulhu1138

mutant is highly unlikely, so you are most likely either adopted or a bastard child.

don't jump into conclusions too soon - double check if your parents' blood type are actually A and O.

#37 - On 04/11/2009 at 9:47pm by changster

this is very interesting haha

#38 - On 04/11/2009 at 9:48pm by christtt315

Bombay phenotypes are if you have an AO and an OO, which would show up as an A.
If you had an AB (genotypically AB) and an OO (genotypically O), it would show as AB.
If you had an AO (genotypically A) and a BO (genotypically B), it would also be AB.
In order to get a B, both parent would have to be a OO, BO, or BB.

#39 - On 04/11/2009 at 9:49pm by imajinethat

lol @ #16!

#40 - On 04/11/2009 at 9:49pm by acertijo

Or maybe, if you're lucky, one of your parents is mistaken about their blood type.

Otherwise, that really sucks.

#41 - On 04/11/2009 at 9:49pm by K4ofDoom

Man, I wish I were a mutant...
Omega level would be suitable enough.

Anyway... have a nice little famjam meeting. If you are adopted, you can use the whole "you're not my real parents!!". If your mother slept with someone else, well, it's in the past... your current father is the one who raised you. Just hope you're a mutant...

#42 - On 04/11/2009 at 9:50pm by _comic_

Well, depending on how the conversation with your parents goes, you may or may not have another FML to share in a little bit. That's good news, right?

See, you have to look hard, but there is always a silver lining.

#43 - On 04/11/2009 at 9:50pm by zachary918

That sucks ass. I'm sorry to hear this.

#44 - On 04/11/2009 at 9:51pm by ass

loooooooool.

#50 - On 04/11/2009 at 9:55pm by Jasper

Quick bio lesson for the people who think it's possible. One parent is A, can't produce a baby with B unless the other parent is B. One parent is O, can't product a baby with B unless the other parent is a B. Neither parents have type B blood. Therefore, adoption or affair. Which is fucked up either way.

#51 - On 04/11/2009 at 9:58pm by Think_Tink

#14 I know what you're talking about, but anyone else would be confused as fuck by that explanation. To better explain that, the Bombay phenotype occurs when a person expresses the O blood type, but has a different genotype (one coding for B, AB, A, etc). It only occurs when the parent is homozygous recessive for a very rare gene that prevents the person from synthesizing the antigens which we use to determine blood type (resulting in the O blood type even though they're genes make them a different blood type). It's more likely that you're adopted or you're not your father's child. However, it is possible, so I would ask your mother about it. Anyways, that's a terrible way to find out, and I'm sorry to hear that.

#52 - On 04/11/2009 at 9:59pm by cadenernest

Yeah, I'm studying genetics and blood types A and O combined can only make blood type A children...so sorry :(

#53 - On 04/11/2009 at 10:00pm by rainesan

#4 just go back into your cave. You don't know what you're talking about.

#55 - On 04/11/2009 at 10:03pm by cadenernest

wait. something is fucked up with comments. anyway the #21 i saw explained how there is a rare condition that allows for this to occur. not saying that it's definitely what happened, but it's another possibility. Bombay was mentioned, but i am almost positive that there is another rare instance where this certain condition can occur.

#56 - On 04/11/2009 at 10:05pm by meddude

Why thankya, meddude. =P

#57 - On 04/11/2009 at 10:06pm by _comic_

i like how science savvy you are, though ; ]

#59 - On 04/11/2009 at 10:12pm by 14hatemachine

I'm gonna go with illegitamite; your parent would've probably told you if you were adopted and mutant is out of the question.

#60 - On 04/11/2009 at 10:15pm by AkihiroHattori5

it is possible that your parents are mistaken about their blood types.

#61 - On 04/11/2009 at 10:16pm by collegegirl8

Who cares? How is this an FML? Your life wouldn't have been altered at all if you hadn't found out, and it doesn't have to be now.

#62 - On 04/11/2009 at 10:19pm by Ohnoitslindsay

you know, sometimes i wish i WAS adopted...

sorry you had to find out that way

#63 - On 04/11/2009 at 10:19pm by Remegy

I'm sure one of your parents is ambidextrous, but has right handed gene.

#66 - On 04/11/2009 at 10:25pm by Dragoslav

HEY look on the bright side maybe just maybe you have some super mutant powers maybe super strength? or laser vision cmon who doesnt want laser vision?

#67 - On 04/11/2009 at 10:27pm by ZiggyMorrison

just wanted to point out that illegitimacy has ABSOLUTELY NOTHING to do with phenotype expressions (whether you are A, AB, or O blood type). illegitimacy just determines if you were born/conceived in or out of wedlock
so yea if you are type B and your parents are type A- and OO then yea AT LEAST one of your "parents" arent biologically your "parent"

#68 - On 04/11/2009 at 10:28pm by kahyia

"My brother and I are right-handed but both our parents are left-handed. Also impossible"

Uh, no...handedness doesn't work that way.

I am B+ and there is no one in my family with B+.
My mom is AB and dad is O.

#73 - On 04/11/2009 at 10:35pm by sugarspyce

HEY maybe you have mutant powers laser vision perhaps?!?! who doesnt want laser vision

#74 - On 04/11/2009 at 10:35pm by ZiggyMorrison

So with mutant out of the question
1) Adopted
2) Your dad knocked up another woman and brought the kid home and your mom reluctantly agreed to raise it rather than divorce
3) Your mom slept with another man and your dad never found out.

I'mma opt for the third option. Confront your mom. She could tell you whether it's 1, 2 or 3 so...

#75 - On 04/11/2009 at 10:37pm by I_Deserved_It

Hmm, well judging from the unlikeliness of that Bombay phenotype that #25 explained and the extreme unlikeliness of your genotype arising from a random mutation, I would say that it's pretty likely at least one of your parents isn't your parent.

#76 - On 04/11/2009 at 10:37pm by skierguy

#13: PER SE. Per se. Spell it with me now, p-e-r s-e.

it is possible

#78 - On 04/11/2009 at 10:41pm by antimony

its not totally impossible. just a 1 in 1,000,000,000,000 chance or somethin like that.

#79 - On 04/11/2009 at 10:49pm by wewas1991

Your parents just wanted to be nice to you and pretend that you really were their child [:
Seriously, though, it is possible, just very unlikely.

#80 - On 04/11/2009 at 10:52pm by losergirl

Your parents have a secret they're going to tell you at some point.

#81 - On 04/11/2009 at 10:53pm by SiLveRStaRLIGHT

You are an illegitimately adopted mutant child.

#82 - On 04/11/2009 at 11:00pm by AWESOM_E

My bio teacher in 12th grade had a similar situation. He used to make everyone find out their parent's blood types while teaching genetics. Some girl, who already knew her blood type, was very confused about how she could have her blood type, given what her parents had.

He stopped doing that assignment.

#83 - On 04/11/2009 at 11:02pm by JoshBarblahblah

The same thing actually happened to MY 12th grade biotech teacher, except it was a little more complicated than blood type. A lot of our labs were dealing with DNA (specifically, gel electrophoresis) and I guess she used to do a lab where you would run your family's DNA and yours and see the similarities etc. Then much as in the situation you described, one day some girl's DNA didn't match at all. She was adopted. Oops.

Sorry you had to find out this way, OP...although, do talk to your mother. Maybe it's not what you think?

Number 16, you're not suggesting that the poster is a chimera are you?
Because it is much more likely that his/her parents have some serioussss explaining to do.
lol

Also number 14, right and left handedness isn't genetic.
It has to do with what hands your parents handed toys and things to you, and which hands you did more things with during the most important motor development stages.

#87 - On 04/11/2009 at 11:12pm by JillianIsLoveee

Geez... you need to speak to your mom privately about this, most likely she slept with the milkman. Then if she doesn't 'fess up, tell her you'll tell dad.

Have you ever heard of recessive(sp?) genes?

#92 - On 04/11/2009 at 11:20pm by aesteppe

You should see if your rh antigen is possible too. If your rh antigen is impossible, then yeah, they're not your real parents. If your rh antigen is possible, then you may just be a mutant and further DNA testing would be able to confirm whether you are indeed a mutant or not the kid of your parents. Whatever the case... FYL.

#93 - On 04/11/2009 at 11:20pm by easrc

Being a mutant woudn't be a FML, unless is came with horrible deformities instead of sweet super powers

It's NOT impossible. My Mom is O- my Dad is A+ and I am O+.... Both my parents ARE my parents.

"Yeah, I'm studying genetics and blood types A and O combined can only make blood type A children...so sorry :("

I know my parents are both the biological parents of my siblings and I. My Mom is O- my Dad is A+ and I am O-.... so I guess you aren't studying too well.

#96 - On 04/11/2009 at 11:37pm by 100308

6, you are dumb. recessiveness has nothing to do with blood type, so it would be impossible for both of his parents to really be his parents. also 38, the positive and negative thing has to do with proteins in your blood, so your situation is posssible but it is different from the O.P's situation. yay biology majors.

Remember, it's not whose blood you took, rather who raised you that makes a father/mother a father/mother. Be glad you have people who raised you, who also love you unconditionally.

#109 - On 04/12/2009 at 12:00am by Nate_87

Yeah, with those parental blood types you would have to be A or O... there is a minimal possibility of chimerism for you or your parents, but most likely one of your parents isnt your parent... and this may really become your dad's FML

#110 - On 04/12/2009 at 12:02am by hooverSP

#113 - On 04/12/2009 at 12:05am by _screamer_

There is at least one other way you could have type B blood, though it's likely you would have known about it before today. If you received a bone marrow transplant, your blood type would change to that of the donor. Blood types do not have to match for bone marrow transplants.

i agree with #11! i always thought my mom was B and my dad was O, so i freaked when i found out i was AB. i casually asked my dad his type, and he was actually A -- i'd just been mistaken. double check with them first!

#118 - On 04/12/2009 at 12:26am by hellohello1

Believe it or not, this actually happens quite often. 10% of children are conceived from an extra-marital affair.

"I know my parents are both the biological parents of my siblings and I. My Mom is O- my Dad is A+ and I am O-.... so I guess you aren't studying too well."

don't quote me, but o is recessive so your mother may have an O- gene. possible fail on your part.

40: This is not possible due to recessive genes. Many things are far more complicated than what you learn in 9th grade. Blood types being not much more complicated. A and B are dominant over O but not over each other (hence AB). If the mother's A she's either AA or Ai, if the father is O he's ii...it's not possible for a B to pop up in there unless something wierd is going on. I can't say it's impossible but I think you have some questions to ask your parents.

more common than you would think - I've heard that some studies suggest in certain industrialized areas of the world, paternity does not match in 10 - 30% of individuals. These studies were based purely on blood types. You're not likely to be a "mutant", though.

#159 - On 04/12/2009 at 3:24am by ggg_unit

Um...I know you've gotten a TON of comments already, but I just wanted to try and make you feel better. I mean, you may want to talk to your parents anyway, cause it IS uncommon, but I'm a biological anthropology major with a focus in forensic anthropology and genetics, and it actually IS possible for a child of two separate blood types to end up with a different one. The average human has six mutations in their genetic structure, and although that doesn't seem like a lot, some of those mutations can evidence themselves quite clearly. Also, it is possible for some genes to be hidden and pop up later, even though they showed no evidence in the parents. We did a specific study citing a case exactly like this in Biological Anthropology when we focused on blood types, and it DOES happen, so...just something to keep in mind.

#160 - On 04/12/2009 at 5:00am by aqua

if your father is O u r adopted
if your mother is O u r either adopted or she cheated on ur father

;)

#161 - On 04/12/2009 at 5:05am by newguy90

OMG! It is freaking scary the number of scientific inaccuracies in this thread.

#156, you are close, but wrong about the Bombay Phenotype. See http://en.wikipedia.org/wiki/Bombay_phenotype#genetics

Yes it is possible, and here is how.
But first some blood SCIENCE.
Blood type O is recessive, but both A and B are dominant. Thus:
-/- is O
A/- is A
A/A is A
and A/A, B/- is AB

So if both parents are O, then the offspring MUST be O.
If one parent is AB and the other is O, then the offspring MUST be either A, or B but cannot be O or AB.
If (p1) is A and (p2) is B, then the offspring can be anything: A, B, AB, or even O, depending on whether or not the parents are homozygous or heterozygous.

Back to the OP's case. There are four genes, eight alleles, four each person, being discussed here. There are actually many more, but these are the "important" ones:
A/A, B/B, +/+, h/h for a homozygous presence.
-/-, -/-, -/-, -/- for the homozygous absence, which would be expressed as phenotype blood type O.

let * represent either (for when it doesn't matter)

If the parents were
(P1) A/-, -/-, -/-, */-, [phenotype blood type A]
(P2) */-, B/*, -/-, h/h, [phenotype blood type O]
can result in an offspring:
(f1) -/-, B/-, -/-, h/-, [phenotype B]

Thus, it is possible.
Note: The h/h Bombay genotype suppresses the expression of A and B phenotypes because the molecular precursor is absent. The h/h genotype effectively hides the genotype of the A, B, or AB blood type. Take molecular biology, cell biology, or metabolism classes to understand this one.


The rest of you: Your high school genetics fails you here. Do not be so quick to think you are an expert and know everything.

OP: You should set the genetics aside and care more about how your parents treat you.

#162 - On 04/12/2009 at 5:11am by Reasonable_man

My guess is your mom is the O, and she cheated?

#163 - On 04/12/2009 at 5:53am by Theos

And here I thought me and my sister were the only ones with this problem. We're both B and our parents our both O. I always did prefer the mutant theory, lol.

number 162's explanation goes far beyond my knowledge of blood science ( GCSE (i'm english) Biology) so i'll go with what he's saying.

but if it wasn't mentioned that either of your parents have this "bombay phenotype" then i would get them to explain!

uhhh idk i think it is possible which is why its confusing that people are saying its not...punnitt square to the rescue A i the genotype of your parents is that( Ai, Bi) soooo their
B AB Bi offspring could either be AB, A, B, or O....i think youre fine.

Well, another option, which I'm not sure if anyone else thought of it: Your mother cheated on your father with a man with type B & thats your biological father. Just a thought but it'd still suck regardless.

#177 - On 04/12/2009 at 10:12am by CommonTruf

If your mother and father both are the blood types they say they are, the only way that they could both be your parents is if one of them is a chimera (really, really unlikely). A chimera is a organism that basically possesses two sets of genetic code, only one of which would show up in something like a blood test. Really really unlikely though

#186 - On 04/12/2009 at 11:33am by MissOtaku

I think maybe you should just ask your parents about it. Even if they didn't want to tell you before, now's a good time. If nothing else, for your own health--what if you needed a bone marrow transplant or something one day? It'd be VERY important to know who your biological parents are, if at all possible.

#187 - On 04/12/2009 at 11:39am by ammali

If the OP's parents are type A and type O, that means one parent is either AA or AO, and that the other HAS to be OO. If one is AA, then the offspring can only be blood type A. If one is AO, then the offspring could be blood type A (A from one, O from other) or blood type O (O from both).

The Bombay PHENOTYPE (hh) is a super rare condition where someone inherits two recessive H gene alleles, and cannot produce A or B antigens as a result. Though their blood type really isn't "O", it's called "O sub h" (they can't safely receive A, B, AB, or O-type blood; only blood from others who have this Bombay condition as well).

However, this has absolutely nothing to do with reproduction, since phenotypically, someone with the Bombay Phenotype is still blood type O, which would still make them "OO". Since the other parents is still AA or AO, it is impossible to get an offspring with blood type B.

Sorry about this, OP. Something similar happened in my anatomy class a few years ago, that almost got my professor fired. However, the parents ended up confessing, so she got to keep her job.

#194 - On 04/12/2009 at 1:33pm by Newo

For all the people who think they actually know genetics and don't here's what it is, plain and simple. There is no way A blood and O blood can make B blood. Let's Punnett this out. If OP's mom is AA (homozygous for A blood), and the dad is OO, which he has to be. Then, no matter what, you get heterozygous for A blood. AO. If the OP's mom is AO (she still has A blood, because A is dominant), and her father is OO, then she can either be heterozygous for A blood or have O blood, but she cannot have B blood. Blood does not work the same as left-handedness and right-handedness. Blood is inherited like blood, and that's it. For the people commenting, at least read a book before making your claims.

Anyway, for the OP. Yes, FYL. Although, being a mutant isn't always bad...lol :)

Kidding, But that really sucks.

#196 - On 04/12/2009 at 2:06pm by GloomySkyz

Hey #195 read #188 and see the error of your ways. There was a case documented where two O type parents had a legitimate B type offspring that was proven to be theirs. The father sued the mother assuming she cheated but she didn't and it brought up this whole matter. So how about you practice what you preach and read a book yourself. :D

Blood type is represented by three different expressions in genes, one for A type, one for B type and one for the protein that will ground them to the blood cell. A lack of the genes that produce A and B will result in O type blood. A lack of the protein to ground them to the blood cell will result in O type blood tests, but they can still produce A and B. If the father was say type OB for blood type and without the grounding protein, he would appear O type on a test but could pass on the B type to his child (because the protein is still transcribed) and because of genetic diversity he would have the grounding gene from his mother who is likely AO for blood type. Bottom line... you got owned.

Wait a second. They same for your story goes for me but I am my parents legitimate child because I look exactly like my mom and have some of they same traits of my dad. I'm real, so its possible that you are legitimate like me and just somehow got B blood.

#201 - On 04/12/2009 at 3:20pm by vesslia

Hey # 197: I'm sure that case was extremely rare. The more LIKELY options are: a mistake in blood typing or the mother having extramarital sex. Statistically, those two are way more likely than a random mutation or other rare condition. Your best bet is to TALK TO YOUR PARENTS to get answers and if they don't have any, talk to a certified geneticist or someone who knows more about genotyping and blood types than random people on the internet.

#202 - On 04/12/2009 at 3:26pm by beckyb

It's OK... I'm a mutant too. Both my parents are left-handed and I'm right handed. That's also genetically impossible... But I look just like my father, so there's no way I'm adopted or a bastard child. Ha. Cheer up! :)

AHAHAHA that's the same with me.. my father is an O positive and my mother claims she's a B.
but my recent blood test says i'm an O positive.. this after my father told me my stepmother isn't my real mother, this B blood type lady is my real mother. my father. is. a. whore.

#210 - On 04/12/2009 at 4:44pm by sunny

The same thing happened to my friend, this was how he found out who his really dad was.

#211 - On 04/12/2009 at 4:48pm by Domiknitrix

#206, you're either really retarded or intentionally trying to confuse people. What does that even mean, "B overlaps O"? That doesn't mean anything.

#210, you confuse me. If your mother is B and your father is O, there's no reason you couldn't be O as well.

#195 and #197 sum it up very nicely, but it's not a "grounding protein" that's missing--it's a fucose group off the glycoprotein. Because that group is missing, neither A nor B antigens can be expressed, regardless of whether the genes say they are there.

In conclusion, it is possible for the O parent to be secretly BO or BB (if at least one of that parent's parents are B or AB), but it is somewhat unlikely. It's more likely that the mother cheated, that the child is adopted, that the blood type test was wrong, or that the results were remembered incorrectly. The least likely option is that the child is a mutant on its own.

People...

It's been statistically shown on BBC news that 5% of children born worldwide...are born and live in families in which they aren't related to the father. Not placing the blame for unfaithfulness on women as it DOES take 2 to tango!

#215 - On 04/12/2009 at 5:31pm by DisturbedDriver

Wow it's amazing how many people assume Google makes them experts on something they're not. If you haven't studied genetics on at least an undergraduate level, stop embarrassing yourself.

It's very simple. A/B/O alleles follow fairly simple genetics (AB are codominant, and each are dominant to O), but there is a FUT1 gene (associated with the "Bombay phenotype") that can override the alleles present at the 'normal' blood type genes.

Basically, it is very possible both your parents are heterozygous for the Bombay allele, meaning that they are both carriers. If you inherited this recessive allele for both, you will express the associated phenotype. And the Bombay phenotype OVERRIDES whatever alleles you have at A/B/O, because expression of the Bombay phenotype prevents production of the A and B antigens EVEN if you have the A or B alleles.

So it's very possible. You could have the regular A/B/O alleles from your parents, but if you have the Bombay phenotype you'll be phenotypically type O even though you possess the A/B alleles.

#216 - On 04/12/2009 at 5:37pm by snoopy2010

To be clearer, here's what likely happened (assuming your parents didn't cheat):

-The Type A parent has the genotype: AO
-The Type O parent carries a B allele (either BB or BO) but is homozygous recessive at the FUT1 gene, meaning that parent has the Bombay phenotype. In other words, this parent still has the B allele but appears Type O phenotypically because of the Bombay phenotype.

-You inherited the B allele from Parent 2 and the O allele from Parent 1. You also received a normal (wild-type) allele for the FUT1 gene from Parent 1, so you do NOT express the Bombay phenotype. Therefore you fall back to the normal blood type genes, where you are likely BO, resulting in Type B.

Everyone is putting too much faith in high school science. Ask your doctor or a biology professor. Blood types are a lot more complicated than A, B, and i/O. There are also contributing genetic factors with other proteins. My freshman year of college, I learned when donating blood that I am A+, while both of my parents are O. I approached my professor, who explained to me that these contributing proteins are what bond the A or the B to your blood cells. It's not A, it's i^A, etc. So one of my parents is i^A,i^O or i^A,i^A, but lacks the bonding protein, while my other parent is legitimately i^O,i^O and has the bonding protein, thus I got the i^A from on parent and the i^O and the bonding protein from the other. Thus, here I am.

Trust me, I know my dad is my dad because my parents were swingers (ew, I know) and there WAS a question of who my father was, but even if my parents hadn't gotten a paternity test (which they did), my dental records are almost identical with my father's (right down to a crooked tooth and a too tall tooth on my bottom teeth).

So it IS possible that your parents are your real parents.

Unfortunately it is also very possible that they aren't. Just give them the benefit of the doubt, or if you are really concerned, approach them. Talk to them about it. You don't even have to accuse them of anything, just say you know it's possible for them to be your parents, but that you interested in knowing if it's the simple explanation or a mutation, because a mutation would be important for you to know were you to ever need a transfusion.

If you've discovered your blood type through donating blood, it is unlikely that they would take your blood if you have a significant mutation, and in such a case, they would notify you as you would be ineligible to donate again in the future (except maybe donating plasma).

#222 - On 04/12/2009 at 6:28pm by rubbertramp

Also, to be fair there are extremely small odds (incredibly extreme) that one of your parents is the mutant and not you. Such as a chimera. But don't count on it because that is so extremely rare that I only felt like throwing it out there for conspiracy theorists. There are cases where women have failed maternity tests (it's sometimes required for welfare cases) due to chimerism, despite having given birth to their child and never having had the children switched at birth.

#223 - On 04/12/2009 at 6:38pm by rubbertramp

As weird as it sound, it actually IS possible for that to happen. DNA has the ability to mutate, and so a child can have a different blood type than both of it's parents. I would know, I'm the AB- child of an A+ and O-. Here's a site that explains it a little better: http://www.thetech.org/genetics/ask.php?id=181

hope it helps!

#224 - On 04/12/2009 at 6:48pm by now_I_know

You should have your test redone. Your sample could have been mixed up in the lab or the lab tech could have screwed up.

#225 - On 04/12/2009 at 7:09pm by salty

im not sure if anyone else said this but #19 is wrong. O is recessive.

#226 - On 04/12/2009 at 8:08pm by walkemskies

none of those outcomes are that bad. apart from the mutant one

#227 - On 04/12/2009 at 8:49pm by love_fml

Amazing how many people here think they're experts on genetics because they've taken a high school biology class.

I'm a senior biology major (who has taken higher level genetics) and this is absolutely possible. #217 has a wonderful explanation - and that is one of the circumstances where this could happen.

I should add, though, that the Bombay phenotype is very VERY rare! It's much more likely that you're not your parents' son or daughter (Sorry!). Unless, ofcourse, there has been a history of the "h" recessive allele in your family and your grandparents are cousins (or related), making either your mother or father a recessive "hh" - thus leading to an apparent "O" bombay phenotype.

#228 - On 04/12/2009 at 9:10pm by skrabbler2

Thank you #216/#217. I think you explained that a little bit better than me(#162).

Rebuttal for #189, read your own link "http://courses.bio.psu.edu/fall2005/biol110/tutorials/tutorial5.htm" Go down to section 11 talking about epistasis. Then think very hard about what could happen genetically with the f2 generation. Its tricky, but its there. Those universities actually agree with me.

For those using punnet squares. You are completing the punnet squares correctly, but are failing to realize that punnet squares ignore effects like genetic linkage, and ignores other interactions in molecular pathways.
You are correctly applying the general rules of genetics they teach in lower division biology/genetics courses; however, when you get to upper division and graduate level courses you learn about the exceptions to the general rule. Cells in real life are absolutely amazing.

#225 also has a good point about human error. The lab might has screwed up your blood test.

#229 - On 04/12/2009 at 9:36pm by Reasonable_man

Blood type is an epistatic gene. Maybe your type O parent doesn't have the gene to make the proteins needed to express blood type and that's why they're type O. They could have the gene for type B but not the gene to make the protein. The lab could have screwed up your test, too.

#230 - On 04/12/2009 at 9:54pm by dreamscreams

or we could go in the different direction and say your mom cheated on your dad and the affair had type B blood

#231 - On 04/12/2009 at 10:05pm by fyourlife616

haha, oh well! atleast you have decent parents.

i hope.

#232 - On 04/12/2009 at 10:12pm by madelinex

You can be type B homozygous, meaning you would have either a different mother or father who was type B and passed on the B gene, and the other parent which could have been either of your parents could have passed on the recessive gene. You are probably illegitimate or adopted, but I don't see what's wrong with option 2? How is that a fml?

#233 - On 04/12/2009 at 11:07pm by metallicmagic

I never knew being adopted was a bad thing..

#234 - On 04/12/2009 at 11:59pm by Panda25

Actually, its possible because of the bombay phenotype. If the dad was AiPP (Ai - A bloodtype, heterozygous; PP for attachment of antigen to blood cells) and the mom is Bipp, or BBpp (B bloodtype, pp for bombay phenotype, no attachment of antigen), then the offspring could be BiPp, allowing there to be B bloodtype, because he is inheriting his mother's B blood even though her PHENOTYPE is O. Not likely, but possible

PARENTS' BLOOD TYPES POSSIBLE CHILD NOT POSSIBLE CHILD

#238 - On 04/13/2009 at 1:45am by BonitaLee

Find out if the mailman has the same blood type as you.
Simple answer, but your mom would have some explaining to do.
Or you were adopted

#239 - On 04/13/2009 at 2:32am by Stellaritsmeg

Adoption is 4/5 mutation is 2/5 and illegetement child 1/500 those are the odds seeming neither of your parents have B blood type you could be adopted and thats fine my best friend is adopted do you have any second languages?Try reading something in a diffrent language then english if you understand it then that could also mean your from the place that people speak that language if you have never taken spanish class try to read this Hola mi amigo como estas? now what does it mean? and, another possiblity that you did not list is affair? i know thats the last thing u want to know that your mom cheated on your father or had sex before then and had not fertilized yet.it is possible in alot of cases such as this its a big possiblity aswell as adoption.so try to do some research talk to your parents tell them that you found out your a B blood type and ask them and if they dont feel like talking about it infront of the other spouse take them both seperatley and record the results in a nootbook cause they most likley have alot of stuff to tell you.Before this takes up the whole page better be saying goodbye.try to read through other comments and see what other people say. alot of people are gonna say to talk to them.Goodbye and godbless

#240 - On 04/13/2009 at 5:02am by youtubegurl_lily

It actually is possible. I am B+ and both of my parents are a different blood type then me and I am definitely both of my parents biological child. Here is how this is possible:

This is for blood type:

PARENTS' BLOOD TYPES POSSIBLE CHILD NOT POSSIBLE CHILD
A and A A, O B, AB
A and B A, B, AB, O no
A and AB A, B, AB O
A and O A, O B, AB
B and B B, O A, AB
B and AB A, B, AB O
B and O B, O A, AB
AB and AB A, B, AB O
AB and O A, B AB, O
O and O O A, B, AB

And this is for Rh status (what makes it positive of negative):
Mother's Group
Father's Group Rh + Rh-

Rh + Rh + Rh +, Rh -

Rh - Rh +, Rh - Rh -

I hope this helped you.

#241 - On 04/13/2009 at 9:48am by BonitaLee

Okay first of all fuck you for thinking "FML" over being adopted. If you are adopted at least someone cared about you enough not to leave you for dead or abort you. Be fucking grateful. I always believe parents should tell their kids if they're adopted from the moment they can understand the concept--I've always known I'm adopted and it's not a difficult concept to deal with. But it's not something to freak out over. So, fuck you. I realize you also said "mutant" and "illegitimate" but those are not as likely as adoption.

Secondly, you're an idiot. Read the post above me.

#242 - On 04/13/2009 at 10:08am by audiogasmic

I don't believe the FML here is being adopted, so much as the way the OP found out. Who wants to find that out from a blood test and then have to go home and confront their parents for the truth? OP's parents raised him and took care of him, and he should not forget that, but he's just found out that a fact he has accepted for his entire life is probably not true. It is completely understandable that that would be earthshattering and difficult.

#326 - On 02/23/2010 at 1:42am by talaina

Also possible if you were given a total blood transfusion after birth.

#243 - On 04/13/2009 at 10:35am by maybe_next_time

in a way, its kinda funny at the thought of u possibly being a mutant. but all in all, that blows.

#244 - On 04/13/2009 at 11:40am by Vtlacey

have you asked the mailman what type he has?

#245 - On 04/13/2009 at 11:48am by iEnjoy3_14

And it is possible that you may be your parent's children. There's something called a chimera, and that's where you're made up of cells from your body and someone else's. This happens plenty of times, especially if you have an older sibling. So that means that while genetically you may not be your parent's child, you may actually be their child anyways. It would be interesting to see if you were your aunt's or uncle's child.

Recessive genes bruh.

#252 - On 04/13/2009 at 4:02pm by ideclarewar

...the parent with A could be AB when crossed with O which would make you BO, B being dominant making you bloodtype B

@ #251. You need to go back to Biology. Again, it's called co-dominance.

#261 - On 04/14/2009 at 7:44pm by Program

this is possible...
its called Bombay Allele - AKA Bombay blood.. very rare
its like epigenetics, some allele can mask the gene type for B, but you can pass on the type B to your child..
look it up

#278 - On 04/19/2009 at 11:32pm by wordgirl

To all those who are saying it isn't possible: it is. The Bombay phenotype makes you look like you're group O when you might actually be B (or AB, or A)... maybe you should take five minutes to look it up before telling us to "take someone else's word for it".

#279 - On 04/20/2009 at 8:41pm by xarrium

If bombay phenotype is about the O type how does it have anything to do with a type B? O is almost a recessive blood type, you could be AO and show up as A.

I'd double check with your parents before jumping to conclusions.

#280 - On 04/23/2009 at 2:47pm by beerab

Actually more than one gene controls blood type. If the gene that makes the 'stem' for the antibodies that cover red blood cells are not created because of the recessive phenotype of the gene that codes that, no antigens are made for the blood, making it seem as though the blood is type O, which also has no antigens in the blood. So it could just be a different recessive allele other than the one that codes for blood type. You might just be okay.

#281 - On 04/24/2009 at 1:49am by lindsayfabulous

well there are both dominant and recessive alleles. Estimating that both your parents are A and O their recessive allel is b. this leaves the options Ab, Ob, AO, and bb so bb is probly what you have guessing that their recessive is b

"My daughter of a past affair I have hidden from my husband, finally turned 18 and went off to donate blood. Which she of course found out was type B.

Dude that really sucks, that basically means you're adopted. I'm sorry man. Even if one of your grandparents had B, that doesnt affect blood type. Blood type is strictly from your parents. :(

#286 - On 05/02/2009 at 10:30pm by gridiron3

for your information it IS possible for you to have a totally different blood type.

There was an article about how a teen commited suicide because his blood type was different from his parents. But in fact his parents were his actually parents.

Mutation is not a bad thing, so don't be so paranoid about having a small mutation in the blood type.
at least you don't have Down symdrome.

#287 - On 05/15/2009 at 2:38am by johnjason

It is possible actually my Mom and Dad are different blood types and most of the kids in the family are 0 positive, my mom and Dad are A's and B's

#288 - On 05/21/2009 at 1:49pm by pocketrockets

well im a genetics student and i can tell you that its possible that theres nothing weird going on and youve just got a mutation in the gene, but thats nothing to worry about since that mutation is shared by over 10% of the world... but in all fairness thats unlikely and your probably not your fathers child...but imo who raised you is more important than who had sex with your mother...

#289 - On 05/25/2009 at 8:56pm by dougal

#294 - On 06/06/2009 at 12:14am by lolololcheese

Okay guys - this is simple biology here. It's 7th grade stuff, not rocket science. Everyone has two blood type genes, one from their father and one from their mother. The blood type means the markers on your red blood cells. A marker - type A. B marker - type B. Both - AB. Neither - O.
Now, the mother is type A. That is her phenotype. Her genotype is the two genes she received from her parents. This can be either AA or AO because O is recessive. The father's genotype is O. His only possible phenotype is OO. Alright. Now the only two genes present here are A and O. Because the father cannot have an A, these parents can only produce an AO or OO child, or type A and O. Therefore, in order to be type B, either the mother is really AB or the father is actually B, because yes, type A and B can make B if the type A is genotype AO. Okay? Okay. Sucks for OP though... could be sperm donor, or one of your parents forgot their blood type, or mom cheated, or you're adopted. And sorry for having such a long comment.

#300 - On 06/19/2009 at 6:07am by tblack147

Oh yes to the guy above saying the only determining factors are A B and O that's not true his father prolly had OOi to the b ( I say this because I am unable to make exponents) and his mom prolly had AOi to the b and Oi to the b with Oi to the b makes B type blood. So these other not commonly known factors can make this blood type possible tho it is not very likely, yet still possible. So good news kid it's possible

#301 - On 06/19/2009 at 6:17am by tblack147

If you are adopted or illegitimate you still have two parents that love you, right?

I'm adopted and when people ask me about my real dad I say "he's right here" pointing to adoptive father.
^^

#302 - On 06/27/2009 at 3:06am by michaelsgirl

I read up on this and it seems that if one parent was OB that there is a one in four chance of you being B. Other factors are also organ transplants that can change blood group especially bone marrow. Or it may be your parents have no idea. But there are other reasons than the general norm, like one parent being OB.

#303 - On 07/13/2009 at 1:56pm by sue43

#303 just no... they said a parent was A and O. If youre OB you are a B not an O or an A. They prolly wouldve told u ur adopted so im guessing either your mother gotta a little too friendly with someone she shouldnt have... or are you certain your parents were married when you were 'conceived' ? thats a perfectly logical, nothing wrong with explanation.

I'm a third yr genetics major (so don't declare I'm wrong coz you high school bio teacher says so)

It's possible that your mum has a rare recessive mutation that affects the protein that attaches the A/B antigen to the cell. So you mum could be B or AB but because the antigens don’t attach to the cell membrane they can't be detected and she appears to be O even though she's not.
Or she could be bombay

If you want to know you should ask you mum privately coz if she didn’t cheat you’ll ruin her marriage

#312 - On 09/27/2009 at 11:50am by hvcdxfd

Hey there - First off I would like to say congrats to all the idiots out here that CANT do the math -- they were close.

SO your DAD is O your MOM is A? (lets say)
AND YOU ARE B!

Now, I can tell you this -- there is a HIGH CHANCE THAT indeed you ARE their kid!
Don't listen to all these idiots. It is your Dad who is really B - If your DAD is O, supposedly - he is the one that gave you the B . Here is how i will break it down for you -- B=O?

OK, so people who are marked as O blood type ARE not always O blood types - there is something called ANTIGEN HH This antigen when surfacing on your blood platelet - tells people when they are testing you you are O but your not!!!
So- if you are sure your dad is your dad - understand this that - you have inherited his B as he is BO and mom AO or vice versa - as only that combo would give AB:AO:BO:OO , AO and BO are phenotype fro A and B consecutively -

SO there -- your mystery is solved!! Yes it is highly possible that they are your parents - If you don't think they lie to you , or you got your mom or dad's toes etc.. then this is the case... AND as a check - you can ask you dad or mom whoever is O to get an ANTIGEN HH test - it is a specific test that will seek it out -- and then you will TRULY know.

Remember this BOMBAY PHENOTYPE means it looks like O cause it presents the antigens but it can be A, B , or AB underneath!!

It's not an FML if you are a mutant. You can be like Wolverine!

Dear 314 (and others),

You are incorreect. If he is correct about his parents blood types (and you'd be surprised how many people don't know what their blood type is, or remember it incorrectly), then he is not their child. Assume that his mom's genotype (what her actually genetic blood type is) is AO. Then her phenotype (what her blood type looks like) is A. Assume the father is OO (what he MUST be if his phenotype is O). There is now way they would produce a child that is B. ( If the father were genetically BO, he would type as B).

The Bombay blood type is extremely rare. If, as you suggest the father is a para-bombay with B, then he would still type as B.

Ok, it's official, you're a mutant

F your life, and that sounds like my last science assessment. Right down to the blood types. Is your name Matthew, by any chance?
