Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error).

Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.

Genetic drift can have major effects when a population is sharply reduced in size by a natural disaster (bottleneck effect) or when a small group splits off from the main population to found a colony (founder effect).
