Polygenic Traits Exhibit ____ Phenotypes Within a Population

Question

Polygenic traits exhibit ____ phenotypes within a population.
A) only one
B) many
C) two
D) three
E) None of these answers are correct.

Accepted Answer

Polygenic traits are controlled by multiple genes, and each gene can have multiple alleles that contribute to the phenotype. This results in a continuous range of phenotypes within a population rather than just one or a few distinct phenotypes. Therefore, polygenic traits exhibit many phenotypes within a population.
