Answer:The cross between heterozygous father ( blood group B) and heterozygous mother (blood group A) is carried out.

The the four blood groups are controlled by three alleles, IA, IB and IO. Both IA and IB are dominant over IO. When together , since they both are dominant, show the phenomenon of co-dominance, forming the blood group AB.
