Detailed explanation-1: -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.
Detailed explanation-2: -Both A and B alleles are dominant over O. As a result, individuals who have an AO genotype will have an A phenotype. People who are type O have OO genotypes. In other words, they inherited a recessive O allele from both parents.
Detailed explanation-3: -An individual’s phenotype is determined by the expression of antigens on their red cells.
Detailed explanation-4: -There are 4 main blood groups defined by the ABO system: blood group A – has A antigens on the red blood cells with anti-B antibodies in the plasma. blood group B – has B antigens with anti-A antibodies in the plasma. blood group O – has no antigens, but both anti-A and anti-B antibodies in the plasma.
