A gene showing codominance has

Question

A gene showing codominance has (A) alleles tightly linked on the same chromosome. (B) alleles that are recessive to each other. (C) both alleles independently expressed in the heterozygote. (D) one allele dominant on the other.

Tardigrade Admin · Accepted Answer

Both alleles are independently expressed in heterozygote during codominance. In codominance, the alleles of a gene pair are fully expressed resulting in offspring with a phenotype that is neither dominant nor recessive. Example: ABO blood group system.
