Answers (1)


Statement I and III are correct

The population's allelic frequency may change if some individuals leave the population. The shift in allelic frequency is substantial only if migration occurs in a small population. Disruptive selection supports both extreme phenotypes, as opposed to directional selection, which only prefers one extreme.

Option 3 is the correct answer.
