The ABO blood groups in a population is formed by two co-dominant alleles (IA) and (IB), and one recessive allele (i), also represented as (IO). Thus blood group A has two genotypes (IAIA and IAi) , Blood group-B has two genotypes (IBIB and IBi) , Blood group AB has one genotype (IAIB) and Blood group O has the recessive genotype (ii).
