Genetic drift results in a change in allele frequencies because
A) the population has not yet stabilized.
B) gene flow within the population allows alleles to flow between populations.
C) the population size is so small that chance occurrences can alter allele frequencies.
D) the population is so large that natural selection has little noticeable effect.

Question

Quizplus · Accepted Answer

Genetic drift refers to random fluctuations in the frequencies of alleles within a population, especially in small populations where chance events can significantly impact allele frequencies. This is not related to the stability of the population, gene flow, or the size of the population in terms of natural selection's effect.
