If a mother is AB- and a father is O .. would they have A babies?

I can't find this anywhere.. help please



They could..The mother has an equal change of giving the A or B allele to her offspring. All of her kids will receive an Rh- allele from her. The father will give the O allele no matter what. The father may be heterozygous ( /-) or homozygous ( / ) for Rh factor. If he is homozygous all of the children will be Rh . If he is hetero his children will all have a 50/50 chance of being Rh or Rh-





So the possible blood types for their offspring are:


A


A-


B


B-





Use a punnett square if you're confused.




They could, yes.





The mother has both the A and the B, both of which are dominant genes. The father only has 0, which is recessive.





The baby can only get A or B, not AB and not 0, since it will only get one gene of the mom and one of the dad.





About the positive and the negative: The baby can get both, since the parents offer both. Problem for the mom is, though, that when giving birth of a positive baby, there is the possibility that the babies blood will mix with the mother's blood and then the mother will produce anti-Rhesus, making it impossible to give birth of another positive baby. But then again, there are injections for that.




yes, they can have A or B babies.
