Abstract
By the genetic drift, or more strictly, by the random genetic drift in the narrow sense one usually means a random process of variation in gamete concentrations due to the effects of sampling alone at the change of the generations. Initially, the biologist who had paid attention to this phenomenon stressed the important role the drift played in reaching the genetic homogeneity under considerable variations in the population size (causing cancellation of some genetic variants when the size decreases), or under the presence of rare genes (which may happen to be absent in the next generation by pure chance). The situation is however the same when the population size is constant and the gene concentrations are arbitrary in the population.
