Best Answer

No.

The Mother is IAIB and the father is ii. So, in gamete formation, the mother will produce IA and IB, while the father only produces i. When the gametes fuse, there will be two possible genotypes (and phenotypes) for the baby: IAi (A blood type) or IBi (B blood type). The Rh factor (+ or - ) has no relevance in this question, really.

The REAL father can be either: IAIB, IAi, or IBi.

The child MUST get an IA or IB allele from the father.

What will be the blood type of baby of father B and mother AB?

Depending on the genotype of the father BB or BO (BO is probably more likely), the child could be. AB, BB, BO or AO. If the father is BB the child can only be AB or BB. If the father is BO the child could be AB, AO, AO or BB.


Father has b positive and mother o negative can the baby be a negative?

No, the baby cannot be A-. A and B genotypes are codominant and O is recessive. Since the father is B and not AB, his genotype must be either BB or BO. The mother is OO. So there is no way for them to have an AO or AA baby. The baby can be Rhesus negative however, because the father may be heterozygous for the Rhesus factor.
