Gene flow differs from genetic drift because it is the transfer of alleles or gametes from one population to another. It happens when a population migrates or becomes geographically isolated. This is different from the genetic drift seen with the founder effect where the new group is formed in an area that does not … See more In genetic drift, alleles change frequency within a population due to random sampling. As a result, it does not produce adaptations. Two … See more Natural selection is like genetic drift but with one major difference—it’s not random. And unlike genetic drift which can be helpful, … See more WebIn population genetics, gene flow (also known as gene migration or geneflow and allele flow) is the transfer of genetic material from one population to another. If the rate of gene flow is high enough, then two …

Genetic Drift vs. Gene Flow vs. Natural Selection
