How does genetic drift change the gene pool
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. WebA change in the frequency of gene variants, alleles, in a population, typically occurring over a relatively short period of time. Gene Flow (Migration) The transfer of alleles from one population to another, resulting from the movement of fertile individuals or their gamete. f Gene Flow or Migration REMINDER:
