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. … WebIn a population of 100, that individual represents only 1 percent of the overall gene pool; therefore, genetic drift has much less impact on the larger population's genetic structure. The Bottleneck Effect Genetic drift can also be magnified by natural events, such as a natural disaster that kills a large portion of the population at random.
