Answer:
Human blood type is determined by codominant alleles. There are three different alleles, known as IA, IB, and i. The IA and IB alleles are codominant, and the i allele is recessive.
The possible human phenotypes for blood group are type A, type B, type AB, and type O. Type A and B individuals can be either homozygous (IAIA or IBIB, respectively), or heterozygous (IAi or IBi, respectively).
The relationship between blood type (phenotype) and genotype is shown in the link below. The mother (blood type A) and father (blood type B) could be either homozygous or heterozygous .
