Description of genetic drift

WebGenetic drift, also known as allelic drift or the Wright effect, [1] is the change in the frequency of an existing gene variant ( allele) in a population due to random chance. [2] Genetic drift may cause gene variants to disappear completely and … WebGenetic drift involves changes in allele frequency due to chance events – literally, "sampling error" in selecting alleles for the next generation. Drift can occur in any …
