WebGenetic drift, also known as allelic drift or the Wright effect, is the change in the frequency of an existing gene variant in a population due to random chance.. Genetic drift may cause gene variants to disappear completely and thereby reduce genetic variation. It can also cause initially rare alleles to become much more frequent and even fixed.
