Question

Which term refers to the genetic control of continuously varying traits such as height?a. incomplete dominanceb. codominantc. polygenicd. multi-allelice. pleiotropic

Answer 1

c. polygenic

Step-by-step explanation:

Polygenic trait is trait that is controlled by more than one gene. This is different than Mendelian genetics in which one gene controls one trait (e.g. flower color). Expressed phenotype is mix of all genes that control it (each gene has the same influence on phenotype).

Traits that are polygenic are height, skin and hair color, intelligence etc.
