epistasis and polygenic inheritance

Answer 1

The correct answer is codominance and multiple alleles.

In humans, blood types are determined by the ABO blood group system, which involves multiple alleles (IA, IB, and i) and exhibits codominance, where both IA and IB alleles are expressed in individuals with type AB blood.
