The most common effects the genetic bottlenecks and founder effects are discussed in the article.... Genetic drift is the process of changes of allele frequencies over generations in a random fashion. Genetic bottlenecks and founder effects are the most common effects of genetic drift.The rate of loss of alleles in a genetic drift is Â½ N where N is the number of individuals in the initial population.he effect of genetic drift is inversely proportional to the size of the population. In small populations, most of the individuals tend to be homozygous for deleterious genes. The situation is similar to the effects of inbreeding.
