Which of the Following Does Directional Selection Favour

Question

Which of the following does directional selection favour?
A) intermediate phenotypes
B) phenotypes at one end of the distribution
C) phenotypic extremes at both ends
D) heterozygotes

Accepted Answer

Directional selection favors phenotypes at one end of the distribution, leading to a shift in the population's phenotypic distribution toward that end. This type of selection tends to reduce genetic diversity by favoring a specific trait over others.
