Genetic drift is a result of population fission.

Question

Quizplus · Accepted Answer

Genetic drift refers to the random fluctuation of allele frequencies in a population due to chance events. Population fission, which is the splitting of a single population into two or more smaller populations, can lead to genetic drift as the new smaller populations may have different allele frequencies than the original population. As each of these populations experiences genetic drift independently, the allele frequencies in each population may diverge over time.
