C) incomplete dominance
D) polygenic inheritance

Question

In incomplete dominance, the phenotype of heterozygous individuals is a blend of the phenotypes of the two homozygous individuals. This occurs when the dominant allele only partially expresses itself, resulting in a phenotype that is intermediate between the two homozygous forms. For example, when a red-flowered plant and a white-flowered plant are crossed and the offspring have pink flowers, this is an example of incomplete dominance.
