Each of us has an ABO blood type,which describes whether two characteristics called A and Bare present. Every human being has two blood type alleles(gene forms), one inherited from our mother and one from our father. Each of these alleles can be A, B, or O. Whichtwo we inherit determines our blood type. The table showswhat our blood type is for each combination of two alleles.We inherit each of a parent's two alleles with probability0.5. We inherit independently from our mother and father.
