The founder effect is the reduction of genetic differences that happens when a new species is founded by a limited number of people from a larger group, according to population genetics. Ernst Mayr was the first to thoroughly explain it in 1942, based on previous theoretical work by people like Sewall Wright. WebThe founder effect occurs when the genetic structure changes to match that of the new population’s founding fathers and mothers. Researchers believe that the founder effect was a key factor in the genetic history of the Afrikaner population of Dutch settlers in South Africa, as evidenced by mutations that are common in Afrikaners but rare in ...
WebThe bottleneck effect is a type of genetic drift. Genetic drift is when the frequencies of alleles change in a population based on chance events. The change in frequency is totally random, and there is no pressure selecting for particular alleles. Genetic drift is different from natural selection, which is a process in which a population slowly ...
