Yes, a child with B+ blood can have a father with A- blood. In order for this to occur, the mother would need to be B+ or AB+ and the father would need to be heterozygous.

Father AB positive and mother B positive can child be A negative?

Yes, it is possible for parents who are AB positive and B positive to have a child who is A negative. This is because a child can inherit one A and one Rh negative gene from the parents, resulting in blood type A negative.


What blood type would a child be with a AB neg mother and O positive father?

The child would most likely have either blood type A positive or B positive. A child inherits one blood type allele from each parent, so with an AB negative mother and an O positive father, the child could receive the A allele from the mother and the O allele from the father, resulting in blood type A positive. Alternatively, the child could receive the B allele from the mother and the O allele from the father, resulting in blood type B positive.


Can an a positive father and an b negative mother have an ab negative child?

yes it dependsupon the genotype and phenotype


Can a o positive mother and o negative father have a b negative child?

Yes, it is possible for an O positive mother and an O negative father to have a B negative child. The child would have inherited one O gene from the mother and one O gene from the father, but could have received a B gene from each parent, resulting in a B blood type. The negative Rh factor would have also been inherited from the father.


Can an A positive mother and a B positive father have an O negative child and why?

Yes, it is possible for an A positive mother and a B positive father to have an O negative child. This can happen if both parents are carriers of the O negative blood type, which can be inherited from ancestors. In this case, the child would inherit one O gene from each parent, resulting in an O negative blood type.
