Even thought they have different blood types they can still be from the same father. That's why when some one in the family needs a blood transfusion occasionally some of the family members can not give blood

Is it possible for a mother to have a positive blood type and father b positive to have a baby with ab negative?

Yes -- There is not one gene that determines blood type. The father can be heterozygous for the A blood type. This just means that the father has one A gene and one O gene. Since the A gene is dominant, the blood from the father tests as A. A separate gene determines the positive and negative part of the blood grouping. This is the RH factor. Again the father can have one gene that is positive and one that is negative, positive is dominant. Same analysis for the mother, mixed B and O genes with B as dominant, positive and negative for RH factor, positive dominant. The egg from the mother could contain the B and RH negative (50% chance of each). The sperm from the father could contain the A and RH negative. Thus the baby would be AB negative (no positive from either parent).
