WebNov 4, 2024 · Mutations must not occur to introduce new alleles to the population. No gene flow can occur to increase variability in the gene pool. A very large population size is required to ensure allele frequency is not changed through genetic drift. Mating must be random in the population. Natural selection must not occur to alter gene frequencies.

WebEvolution by genetic drift causes changes in populations by chance alone. Evolution by genetic drift occurs when the alleles that make it into the next generation in a population are a random sample of the alleles in a population in the current generation. By random chance, not every allele will make it through, and some will be overrepresented ...
