Is it possible for siblings to have 3 type of blood types (A+, B+, O+) when we have the same set of parents?

1 sister have B+
1 sister have A+
1 sister have O+
Answers:
yesone parent is blood type A+, and the other is B+.Therefore, can be represented as AO, and BO.in this way, it is possible to have an AB, AO, BO, and OO blood type, more commonly known as AB, A, B, and O
I'm honestly not sure,
yes one parent is AB+ with the o genome. The other parent is O+
It doesn't sound unlikely. I was watching TLC and this mother was getting welfare and they had to get a paternity test on the mother and father, the father came up fine, but the mother was negative. She got about four tests done, and she KNEW the babies were hers, they just didn't happen to share the same DNA. Weird huh? I guess anything is possible.
you should have either your father or your mother's blood type. One of you is a bastard. Sorry.
Yes.
Yes, one of your parents have blood type A and the other has B. I'd explain in terms of heterozygous and big I and little i and Punnet squares, but I don't think that's necessary. Basically yuor parents genotypes are I(A)i and I(B)i.
It is very possible. If one parent has a BO+ genotype (their blood type would be B+), and one parent has a AO+ genotype (their blood type would be A+), then all of those combinations are possible. _|B___O
A|AB |AO|
O|BO |OO|Above is a simple Punnett Square. One parent's genotype is shown on the top, and the other goes down the side. 25% of the children will have genotype AB, with AB bloodtype. 25% will have genotype BO, with B bloodtype. 25% will have gentotype AO, with A bloodtype, and 25% will have genotype OO, with O bloodtype.It couldn't work if one parent was AB and one was OO, because A and B are both dominant over O, and each child recieves one from each parent, then every combination would be either AO or BO, bloodtype O wouldn't be possible.
yes. your parents probably have the alleles AO and BO.each sister will have inherited the one allele from each parent. so they have BO, AO and OO respectively
