Question

What term describes a trait that is controlled by many genes?
A) dihybrid
B) dominant
C) heritable
D) polygenic

Accepted Answer

A trait that is controlled by many genes is called polygenic. This means that the trait is determined by the combined effects of multiple genes. Dihybrid refers to a cross between two individuals that differ in two traits, while dominant refers to a gene that is always expressed over a recessive gene. Heritable means that the trait is able to be passed down from one generation to the next.
