Genetic drift

Vedclass · Answer

(D) Genetic drift refers to the change in the frequency of an existing gene variant (allele) in a population due to random sampling of organisms. In small populations,chance events can cause allele frequencies to fluctuate significantly from one generation to the next. This process can lead to the complete elimination of certain alleles or the fixation of others,which is a key mechanism of evolution distinct from natural selection. Therefore,the chance elimination of genes from a small population is an example of genetic drift.
