In What Size Populations Does Genetic Drift Occur? Typically, genetic drift occurs in small populations, where infrequently occurring alleles face a greater chance of being lost. Once it begins, genetic drift will continue until the involved allele is either lost by a population or until it is the only allele present in a population at
Under What Conditions Is Genetic Drift Most Likely To Occur? Typically, genetic drift occurs in small populations, where infrequently-occurring alleles face a greater chance of being lost. Once it begins, genetic drift will continue until the involved allele is either lost by a population or is the only allele present at a particular gene locus
How Do You Test For Genetic Drift? to test for genetic drift. According to the theory of genetic drift, the variance in allele frequency across the populations should increase by a factor of p(1 –p)/2N each generation, where p is the current frequency and N is the population size. How do you know if genetic
