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

162: Several universities disagree with you. Sorry. http://www.biology.arizona.edu/human_bio/problem_sets/blood_types/02Q.html http://studentorgs.vanderbilt.edu/vsvs/New%20VSVS%20Site/Web%20Lessons%202006/Inheritance%20and%20Blood%20Typing/Inheritance%20and%20Blood%20Typing.pdf http://courses.bio.psu.edu/fall2005/biol110/tutorials/tutorial5.htm To anyone less vapid than 162, read up.

for all of the people who are saying that it is possible, there are certain conditions (if the father was a chimera or had bombay phenotype) but those are so unlikely that its not even worth pointing out.

uummm... you're wrong... get over yourself unless your parents are like white and you came out looking half-black

1) Blood Typing Wrong 2) Your Mom cheated 3) Highly unlikely that your dad cheated and got the child 4) Adopted 5) Fertility experiment. Your mom's eggs or your dads sperm, ZHEY DO NOTHING! 6) Your dad got some kind of freakish ******** transplant and had sex wayy to soon to flush out all the stored up sperm with his own. lol

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 :)

A lot of people are way too strident on this tread. Remember that scientific explanations are only ever "the best model" until a better or more refined one comes along. In this case, yes, you are right; basic genetics considering a single gene at a time gives you what you say. That does not make the OP's situation impossible. It makes it difficult to explain with basic genetics. However, humans are very complex and there are frequently variants of other relevant genes in the population. See 162 or 52 for good explanations of the Bombay phenotype. Chimerism is also a possibility. "Epigenetics" is an emerging field in which all sorts of strange patterns of gene expressino are bing found. I'm sure that a specialist in blood genetics could tell you of others and there are almost certainly further refinements that nobody is yet aware of. They may be very rare but that's different from "impossible". Remember that every scientific explanation should begin with "As far as I understand it". Others will understand more. Even if that's the best known explanation now, in 200 years' time someone will have found something better. Keep learning everyone!

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.

wow #3 really? fawkes was considered a mutant among super mutants tho :P (fallout 3 in case ppl dont kno wat he was talking about) lol....and i doubt the person writing this fml wants to look like fawkes xD
