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

Someone else could have gotten your mom pregnant and had that blood type...

Wow, this is exactly what happens in my favorite book, Lancelot. I'm favoriting this just for that. and #179, that's what an illegitimate child is :P

My ex is A, I am O, when my son was born B I asked the nurse how that happened, they explained to me that my O is a bit of everything. It didn't make sense to me, but since I didn't cheat on my ex I have to believe it.

It seems that you are either a chimera or you have this "Bombay" phenotype. Type "O" is not really a type but rather an absence of any other type. Normally you get this because you don't have the A or B genes. In plain language the "Bombay phenotype" means that you carry the genes to be A, B or both but they are "hidden" - they don't show up in your blood because you lack another gene necessary to make them "visible". If they were flashlights, A might be a red bulb and B might be blue. Type A is red light, Type B is blue light, Type O is no light. Bombay means you don't have any batteries! You could have any bulb but the flashlight is still dark, which looks like Type O. If your child got this "missing" gene from their dad then they can show the blood type they got from you. They get batteries from their dad and a bulb from you - hey presto! Suddenly they can show their light. If you're a chimera then you are really two people! Cool but weird and I don't think it's very common.

Too bad you aren't also a turtle (8) Teenage mutant ninja turtles are kind of my love. ;)

THANK YOU #162 PLEASE learn some genetics people.

Your mother's genotype (Ai) and you father's (ii) cannot produce a genotype (Bi) which is yours. Why are people saying this is possible?

It isn't possible and I want to know what idiot believes that this is the OP fault.

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.

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.

Epic. Fail. Read 162 again. Bombay phenotype h/h parent would be the ''fake O'' blood type one, which coud hide O allele(s), A allele(s), B allele(s), or A and B alleles. That parent would (obviously) pass one recessive Bombay allele to the child and could as well pass a hidden B allele to the child. The child obviously not displaying the Bombay phenotype, the other parent passed a normal H allele. OP, if you made up this FML to feed your attention ***** issues, or to entertain readers, next time try this : hh antigen system (aka Bombay phenotype) could NOT explain an FML with ''My parents both have A bloodtype but I have a B allele.'' Now THAT rules out Bombay Phenotype. (But not the chimera possibility.) Be carefull though : Bombay phenotype COULD explain an FML with ''My parents both have AB bloodtype but I have O bloodtype.'' Here, the child could display the h/h antigen system, which prevents the expression of A, B, or both antigens inherited from parents. As other posters wrote, the ''chimera'' or ''Bombay phenotype'' possibilities are extremely unlikely. I'd go with the ''adoption'' or ''cheating/from one's ex partner'' explanations. So OP #189, you are wrong. The links you provided present simplistic situations which do not consider the -very unlikely- Bombay phenotype to avoid confusing students with variations close to nearly impossible to come across. Just for you OP, an other example : You know how O negative folks are called universal blood donors? Well they are not ''really'' universal. People with Bombay phenotype cannot recieve blood from people who are not also h/h. Though they CAN give to others. But hh antigen system is just so extremely unlikely, we still call O negative universal donnors. Bombay phenotype rhesus negative people would be ''over-the-top universal donors''.
