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.
