A male with blood type B has a child with a woman who has blood type A. The child is blood type O. What is the genotype of the male and female?

Answer 1

Because we each inherit one blood type allele from our biological mother and one from our biological father. A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO.
