How genetic drift works
Web2 apr. 2024 · In order to see how genetic drift works, we can perform a simple simulation experiment using a set of random numbers (Cavalli-Sforza and Bodmer 1971). For this experiment, we will start with our usual model of a locus with two alleles, A and a, where the initial allele frequencies are p = 0.5 and q = 0.5, respectively. http://www.biology.arizona.edu/evolution/act/drift/about.html

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.
