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. WebGenetic drift stems from the chance occurrence that some individuals have more offspring than others and, thus, will pass on more of their genes to the next generation. Small and isolated populations are more susceptible to genetic drift. WebGenetic drift refers to spontaneous changes in genomic DNA that can arise in any generation of mouse breeding.
