Identify the correct statement from the following List.
I. The gene frequencies will alter in people when they migrate out of a population.
II. Artificial selection can take the forms of stabilizing, directing, and disruptive selection.
III. disruptive selection favors extreme phenotypes.
IV. Genetic drift is a single-step big mutation.
I, II, III, and IV
I, II, and III
I and III
I and II
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.
