When doing blood type crosses, you will need to know whether at type A or B person is heterozygous or homozygous. All of the offspring are now heterozygous, with genotype of Bb. AB type blood . A two-trait Punnett Square has 16 boxes. There are three different alleles for blood groups (A, B, and O). The mother is heterozygous Type B (I B i). The genotype in each box is equally likely to be produced from a cross. One Homozygous Parent If we have one homozygous parent, then the other is heterozygous. Human blood groups are controlled by multiple alleles. Therefore, the offspring can potentially have one of four allele combinations: YY, Yy, yY, or yy (Figure 1).
