ABO blood types are a good example of multiple alleles.
AA x Bi
1 A x 0.5 B = 0.5 AB
1A x 0.5 i = 0.5 Ai
Genotypic ratio is 1 AB : 1 Ai
Phenotypic ratio is 1 type AB blood : 1 type A blood

There isn't enough information to address this question. Is the female a heterozygote? She could have A-A alleles or A-O because O is recessive so she would express type A as the phenotype in both cases.06/09/21
