Random genetic drift occurs when there is a change in the frequency of a particular allele in a population due to chance events. This is more likely to occur in a small, isolated population because there are fewer individuals and fewer opportunities for genetic variation. In a large population with random mating, genetic drift is less likely to occur because there is more genetic diversity and chance events are less likely to have a significant impact on the overall gene pool.
