What are possible blood types of father if mom is blood type ab negative son is b negative?
Since the child is B negative, the child is getting the B from the mother. The child must get the negative from both parents. From the father, the child must get either a B or an O to go along with the B from the mother. So, the father can be blood type A negative (only AO), AB negative, B negative (either BB or BO), or O negative.
