The difference between codominance and incomplete dominance is best described by which of the following?

Question

In incomplete dominance, recessive alleles are expressed by heterozygotes. In codominance both phenotypes are expressed.
In incomplete dominance, traits are inherited in a form of Mendelian inheritance. In codominance, traits are inherited in a form of complex inheritance.
In incomplete dominance, heterozygotes display an intermediate phenotype. In codominance an allele is only expressed dependent upon the allele interactions at another gene locus.
In incomplete dominance, heterozygotes display an intermediate phenotype. In codominance both phenotypes are expressed.

Answer 1

The correct statement is: "In incomplete dominance, heterozygotes display an intermediate phenotype. In codominance both phenotypes are expressed."
