Genetic Drift

WebSO FAR, we have dealt chiefly with deterministic evolution, via natural selection.. TODAY, we explore the effects of finite population size and inbreeding on genetic variation, and show that this can lead to random evolutionary change (or "drift"). Mutation is, of course, a sort of random genetic change, but genetic drift can work much faster. First we must … Web2.3.3 Gene Flow and Introduction of Genetic Diversity. Gene flow is also called gene migration. Gene flow is the transfer of genetic material from one population to another. Gene flow can take place between two populations of the same species through migration, and is mediated by reproduction and vertical gene transfer from parent to offspring. WebGenetic diversity.
