O+ Mom plus AB+ Dad = O- baby??
Asking for my sister in law... She says she is O+ and her husband's Mom says he is AB+ and their baby is O-. Is that possible?
Update:Mother in law is O+, Father in law is O+ and their son is AB+... supposedly.

The ABO antigen blood group is a single locus on the chromosome, having three allele types: A, B, and O. The A and B alleles are codominant and so erythrocytes will express both A and B antigens if one of those is from one parent and one is from the other parent. A gene locus comes in pairs though because there are two chromosomes. So although a person may have the A antigen (A type), the allele on the other chromosome in the pair might be O type (which is not expressing A or B antigen. If that person marries a person who has an allele on one of the chromosomes, they have a 1 in 4 chance of having a baby that is O-type even though the parents are A or B. if one parent is AB, that means that one allele on one chromosome is A and the other allele is B. It is impossible for a baby to inherit an O-type in that case. Thus one of two possibilities exist:
1) the child's father is not who you think it is
2) the father's blood was incorrectly typed and needs re-typing
There are two different types of protein that can be found on red blood cells. They are controlled by different genes. The first is the ABO blood type. If a person does not produce a protein, they are said to have type O blood. They would have to be homologous OO in order to do so. If the person produces only type A protein, they can have the genotype AA or AO, and are said to be blood type A. Similarly, if the person produces only type B protein, they can have the genotype BB or BO, and are said to be blood type B. If a person produces both types of protein, they have the genotype AB, and are said to have AB blood.
Every person has two genes, one from the father and one from the mother. If the mother is O, and the father is AB, the baby must be AO or BO.
The Rhesus factor is another type of protein, which a person either produces (+) or does not produce (-). I don't know of any way two parents with Rh+ blood could have a child with Rh- blood.
That is not possible. If the father is AB then he can only pass on the A gene or the B gene. If the mother is O then the child would have to be A or B. The negative part is possible, but not the O.
Hi, it is NOT possible for him to be the father. (as already stated here) As far as the rh factor is concerned, that is absolutely possible and as a matter of fact, most children with rh-negative blood types actually have parents who are both rh-positive.
Here are two links to help you understand (both doctor, and medical research sites that give very clear, easy to read explanations)

Hope this helps!
i feel like i am on jerry springer. he is no the father. i am sorry, but looks like her husband is not the father of her child, and she was the one to give herself away. what a shame.
