Question

Quizplus · Accepted Answer

Genetic drift is the random fluctuation of allele frequencies in small, isolated populations. Therefore, small, isolated populations are necessary for drift to have a noticeable effect on genetic diversity. A long period of time may increase the chance of drift occurring, but it is not a requirement. Selection and large-scale migrations are unrelated to genetic drift. Geographic stability may indirectly affect drift by promoting isolation of populations, but it is not a direct requirement for drift to occur.
