Can two o positive parents produce an ab negative with the Rh negative factor?
We are looking for the possible blood types of a baby.Parental information:Mother type O pos = can only be OO with Rh (++) or (+-): Genes O, (+), (-)Father type O pos = can only be OO with Rh (++) or (+-): Genes O, (+), (-)Baby recieves one gene from each parent, making the baby either:Type O, Rh Postive [ OO, Rh (++ or +-) ]Type O, Rh Negative [ OO, Rh (--) ]Therefore answer is NO. Since the parents are both O type, which is recessive, they cannot give an A or B gene since they do not have any.

Can a 0 positive mother and a A negative father have a A Rh's negative child?
Yes. The mother would have to have a heterozygous Rh genotype, so that she could pass on an Rh negative allele to her offspring.
Can a baby have B negative blood if the mother is B positive and the father is A negative?
Either. We know the mother is homozygous recessive rh- rh- for rh factor, so she can only pass on an rh negative allele to a child. However, if the father is heterozygous rh+ rh- for rh factor, he could pass on one of those two alleles to a child. If he passes on the rh+ (dominant) allele, the baby would be rh positive. If he passes on the rh- allele, the baby would be rh negative.
