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. WebMar 17, 2024 · The random sampling style of genetic drift shrinks the gene pool and therefore alters the frequency the alleles are found in the population. Some alleles are completely lost within a generation due to …
