WebThe type (Genetic Drift) refers to an event in which the allele frequency of a population changes. The subtypes, Bottlenecking and Founder effect, are two different concepts. … WebGenetic drift is the process when the frequency of an allele changes from one generation to the next generation in a population. Within each generation, there is a process of genetic drift because sampling variation is necessary.
