ABO BLOOD TYPE Note. Blood type is mentioned above. This is a trait de-termined by three alleles at a single locus. The alleles are commonly denoted A, B, O. These alleles combine to give the following phenotypic blood types: AA and AO (type A), BB and BO (type B), AB (type AB), and OO (type O). Denote the frequencies of alleles A, B, O as p, q
