For white Europeans, the blood groups (or phenotypes) are deduced based on their genotypes. The phenotype for O1vAv is group A, but whether it is group A1 or A2 cannot be determined reliably.
Av1 represents the single new rare A allele and Ov new rare O alleles. For the sake of simplicity, all the different rare O alleles are grouped under the name Ov. Thus, Ov Ov does not necessarily represent a homozygote.
