A) polygenic
B) incomplete dominance
C) multiple allele systems
D) simple Mendelian inheritance
E) codominance

Polygenic

Relating to or resulting from the influence of multiple genes, especially with regard to traits that exhibit a continuous distribution in the population.

Skin Color

The pigmentation of the skin, primarily determined by genetic inheritance influencing the amount and type of melanin produced.

Height
