multiple alleles and epistasis

Answer 1

The correct answer is codominance and multiple alleles.

In human blood types, the ABO blood group system involves multiple alleles (A, B, and O), and the A and B alleles demonstrate codominance, meaning that both can be expressed simultaneously in individuals who inherit one of each (resulting in AB blood type).
