Fixation due to random genetic drift is more rapid in
A) blue-eyed persons.
B) small populations.
C) the punctuated equilibrium model of evolution.
D) the formation of a new species.
E) tropical environments.

Question

Quizplus · Accepted Answer

Small populations have less genetic diversity, making them more susceptible to random genetic drift. When the population size is small, a random event can have a more significant impact on the genetic makeup of the population. As a result, fixation due to random genetic drift is more rapid in small populations.
