ABO Blood Group
A classification system for human blood based on the presence or absence of A and B antigens on the surface of red cells, which determines compatibility for blood transfusion.
Codominance
A genetic scenario where two different alleles of a gene are expressed equally in the phenotype of a heterozygous individual.
Incomplete Dominance
A genetic phenomenon in which heterozygous alleles result in a phenotype that is a blend of the two parental traits.

Final Answer :
E
Explanation :
The inheritance of the ABO blood group is an example of codominance and multiple alleles. The ABO blood group system involves three alleles: A, B, and O. These three alleles exhibit codominance, which means that both alleles are expressed equally in the heterozygous individual. Additionally, multiple alleles mean that there are more than two possible alleles for a particular gene. In this case, there are three possible alleles (A, B, O) for the ABO gene.
