<span>Genetic drift is a
random change in allele frequencies that occurs in a small population. Because there are so few parents in small
populations, the frequencies in the offspring produced may differ from allele
frequencies in the parents. This can result in certain genes disappearing as
individuals die, or do not reproduce. Natural disasters can wipe out certain individuals (or whole parts) of a population. When this happens, genetic drift is the result. </span>
