When the dominant allele does not completely mask the effects of the recessive allele in the heterozygote, it is called ________.

A) dominance
B) polygenic dominance
C) codominance
D) incomplete dominance
E) corecessive

Incomplete Dominance

A genetic phenomenon where the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes, indicating a blend of the parental traits.

Dominant Allele

An allele that expresses its phenotypic effect even when heterozygous with a recessive allele, masking the effect of the recessive allele in heterozygotes.

Recessive Allele

A type of allele that produces its characteristic phenotype only when its paired allele is identical.
