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. WebThe origin (cause) of the mutation: spontaneous mutation arise randomly as a result of an error in a natural process eg DNA replication in cells; induced mutation arise as a result of an environmental agent like chemical or radiation, → increase the chance of changing nucleotide sequences 2.
