1. Genetic drift , the fixation of alleles, will depend on effective population size.2. The mechanisms of genetic drift can be illustrated with a simplified example. 3. The analogy lacks enough of a genetic drift element, to my mind. 4. The species'wide distribution and consequent genetic drift has led to an extensive synonymy. 5. Natural selection and genetic drift sort variation; mutation and gene migration create variation. 6. Genetic drift affects smaller populations more than it affects larger populations.7. This term can encompass genetic drift , mutation bias, or meiotic drive. 8. Fisher conceded genetic drift played some role in evolution, but an insignificant one. 9. "The point is, you don't get that high numbers by genetic drift alone. 10. Genetic drift is often proposed to play a significant role in peripatric speciation.
