To express a polygenic trait:
a. genes must interact with the environment.
b. several genes must act together.
c. multiple mutations must occur in the same family.
d. penetrance must occur.
ANS: B
Polygenic traits are those that result from several genes acting together. When environmental factors influence the expression of the trait, the term multifactorial inheritance is used. When multiple mutations occur in the same family, the mechanism most likely responsible is termed germline mosaicism. Penetrance of a trait is the percentage of individuals with a specific geno-type who also exhibit the expected phenotype.
