Genetic drift is the term that applies to the circumstance of gene frequencies in small isolated populations fluctuating considerably. Genetic drift can occur when a subset of individuals in a population has random differences in their reproductive success or survival, leading to the spread or loss of genetic variants. This can result in changes to the gene frequencies in the population, which can be further amplified in small populations where chance events can have a larger impact.
