PATHOLOGY

Detailed explanation-1: -An excellent example of multiple allele inheritance is human blood type. Blood type exists as four possible phenotypes: A, B, AB, & O. There are 3 alleles for the gene that determines blood type.

Detailed explanation-2: -The gene responsible for the ABO blood group system is I. This gene exists in three allelic forms-IA, IB and i. IA and IB are dominant alleles and i is the recessive allele. Since, three alleles for ABO blood group are found in a population, it is an example of multiple allelism.

Detailed explanation-3: -There are three different alleles for human blood type, known as IA, IB, and i. For simplicity, we can call these alleles A (for IA), B (for IB), and O (for i). Each of us has two ABO blood type alleles, because we each inherit one blood type allele from our biological mother and one from our biological father.

Detailed explanation-4: -Assertion :ABO blood group system provides a good example of multiple alleles. Reason: In ABO blood group system, when /A and JB alleles are present together, they both express their own types.
