Which statement describes the difference between incomplete dominance and codominance?

Answer

In codominance, only one allele is expressed in the offspring; In incomplete dominance, both alleles are expressed in the offspring.

In codominance, both allels are expressed in the offspring; In incomplete dominance, only one allele is expressed in the offspring.

In codominance, both alleles are expressed in the offspring; in incomplete dominance, the offspring demonstrate an intermediate form of the alleles from the parents.

In codominance, the offspring demonstrate an intermediate form of the alleles from the parents; in incomplete dominance, both alleles are expressed in the offspring.

Explanation

In codominance, both alleles are fully expressed, so both traits can be observed in the offspring. In incomplete dominance, neither allele completely masks the other, resulting in an intermediate phenotype between the parents’ traits. Therefore, choice C correctly describes the difference.
