Genetic drift - A variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce.

Daniel Morrison · Answer 2

Genetic drift (also known as allelic drift or the Sewall Wright effect) is the change in the frequency of an existing gene variant (allele) in a population due to random sampling of organisms ... A population's allele frequency is the fraction of the copies of one gene that share a particular form.
