Yes, it is possible that an A negative mother and a B positive father can have an O positive child. Because looking back to the basic of Genetics, Blood Banking, Immuno/Serology. A parents whose blood groups are A and B can possibly have all the blood groups in their offspring (A, B, AB, and O) most specially if both parents blood groups are A and B genotypes. When it says genotype, meaning the parents are either AO or BO. The genotypes are the genes/traits that are not expressed (recessive traits) or are hidden. Meaning that the O gene in an AO genotype blood is not expressed and only the A gene which is the Phenotype in that particular blood group is only expressed (dominant traits) thus showing as a type A blood, and same goes with the BO genotype blood group. So going back to the question if an A negative mother and a B positive father can have an O positive child, then the answer is YES most specially as I mentioned earlier if the both parents are A and B genotype blood group. Then when it comes to Rh grouping (being negative or positive) since both traits are present in the parents (A negative mother and B positive father) then all the offspring can inherit both traits.

∙ 13y agoNo. In this case, the child will have an A, B, or AB blood type.
Also of interest; blood type can function as a simple form of paternity screening. Taking your example here, if an AB type mother has a type O child, that means she has either adopted it, or has the wrong baby.
An AB mother will NEVER have a type O child. No matter the fathers blood type, she will have either an A, B, or AB child.
To flip your example, assuming the mother has type A, baby is type O, and male is type AB, we know without a doubt that he is not the father. The father has either A, B, or O type... it is not possible for an A mother and an AB father to have an O child.
And as a final example, if the mother was A, and the father was B, the baby could be any of the mix. A, B, AB, or even O.

∙ 11y agoYes, an O+ child can have an O- father. As long as the mother has + blood (not necessarily O+).
This is because Rh positive is dominant over Rh negative. So as long as one parent has positive blood, the child can have positive blood.

∙ 6y agoNo, it is not possible. The baby will be either A or B and not O. She can be either Rh+ or Rh-.

∙ 15y agoNo, he cannot. He can have a child with positive Rh, that is perfectly possible, but a man with AB type blood can have A, B or AB children only.
