Human blood type is determined by co-dominant alleles. There are three different alleles, know as I^a and I^b alleles are co-dominant and the i allele is recessive. The possible human phenotypes for blood group are type A, type B, type AB, or type O. Type A and B individuals can be either homozygous (I^A I^A or I^B I^B, respectively), or heterozygous (I^Ai or I^Bi, respectively), A woman with type A blood and a man with type B blood could potentially have offspring with which of the following blood types?
