Random Genetic Drift in the Narrow Sense

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