    Yes, it is possible. If the mother's genotype is AO she will have the ABO blood group A. Her children can receive an A-allele or an O-allele from her. If the father is ABO blood group AB his genotype will be AB. He can give his children an A-allele or a B-allele.

    If the child were to receive an O-allele from the mother and a B-allele from the father the child's genotype will be BO and the child will have ABO blood group B.
