How does genetic drift change the gene pool
WebMar 17, 2015 · The random changes in gene frequencies occurring by chance and not under the control of natural selection are called genetic drift or random genetic drift or sampling error. This theory was advocated by geneticist Sewall Wright in 1930. It explains the change in gene frequency. It is caused due to sampling error.
