14: Relations between cousins are illegal mainly out of tradition and ethics, partly because they have an increased chance of genetic problems. In simple terms, every human has a couple of "bad genes" he would pass on through procreation. If both partners are non related at all, then they are likely to have very few shared bad genes, which would allow their combined DNA to fix most of each other's weaknesses. Relatives, however, share a lot more of these genetic aspects, bad genes included. That's why their children are far more likely to have those problems carried over into their DNA. That still doesn't mean that they'd be "deformed", however. Deformation is an extremely rare occurence, even within incestuous relations between parents and their children, siblings or what-have-you. Most of the time, if a problem does come up, it's "just" that the kids would end up mentally challenged, autistic, perhaps having Down Syndrome. Physical deformations are very unlikely. PS: My explanation above is supposed to be a rough way of creating an understanding for why incestual relations are unfavorable. The biology behind it is vastly more complex and changes a lot of it, but for the random citizen I believe my explanation should be sufficient. Just don't go and tell it to your anthropology friends and professors. ^-^'
Actually, there are states in which it is legal to marry your cousin--and provided the cousins are of opposite genders, the marriage will be recognized in all 50 states. Franklin and Eleanor Roosevelt were distant cousins (she didn't have to change her last name when she married, in fact). As for you, OP, why didn't you just ask her out instead of beating around the bush?
