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. WebMar 17, 2015 · The random changes in gene frequencies occurring by chance and not under the control of natural selection are called genetic drift or random genetic drift or sampling error. This theory was advocated by geneticist Sewall Wright in 1930. It explains the change in gene frequency. It is caused due to sampling error.
