Web23 jul. 2024 · How does genetic drift works? Genetic drift is a mechanism of evolution. It refers to random fluctuations in the frequencies of alleles from generation to generation due to chance events. Genetic drift can cause traits to be dominant or disappear from a population. The effects of genetic drift are most pronounced in small populations. WebDrift is common to small populations, such as those that colonize islands or other isolated habitats, or those that remain after large-scale disruptions (e.g. earthquakes, fire). Think …
