Question

Genetic drift is the random fluctuation of allele frequencies in a population's gene pool, primarily in small populations. This can occur due to chance events such as random fluctuations in population size, founder effects, or bottleneck events. Mutations, gene flow, nonrandom mating, and natural selection can also affect allele frequencies in a population, but they are not primarily driven by chance events in small populations.
