WebJan 26, 2024 · Genetic drift occurs due to the random selection of some alleles to be inherited by offspring. It affects genetic diversity by fixing certain alleles and losing others since the change in alleles frequencies can produce more significant differences among different populations. Genetic drift affects small populations more than large ones … Web9. Genetic bottlenecks occur when a population is drastically reduced in size, leading to a loss of genetic diversity. The founder effect occurs when a small group of individuals establishes a new population, leading to a loss of genetic diversity due to the limited number of individuals that contributed genes to the new population. 10.
