Both extremes of an array of phenotypes are favored in ________.
A)directional selection
B)stabilizing selection
C)disruptive selection
D)gene flow
E)genetic drift

Question

Quizplus · Accepted Answer

Disruptive selection favors both extremes of a trait, leading to the splitting of a population into two distinct groups. Directional selection favors one extreme of a trait and shifts the population in that direction, while stabilizing selection favors the intermediate phenotype and reduces variation in the population. Gene flow and genetic drift are unrelated to selection on phenotypes.
