The gene pool is the set of all genes, or genetic information, in any population, usually of a particular species.
Gene flow is a process of evolution that takes place when genes or alleles move from one population to another. It is also known as the Gene Migration, and that could cause changes in the allele frequency as well as some variations in the gene pool of both populations.enetic Drift. Genetic drift is a mechanism of evolution of biological species that takes place because of the change in the frequency of alleles in a population. These changes in the allele frequency in a population occur randomly.
