PLse Do Explain this. What is Genetic Drift?
Asked by padminik | 24th Mar, 2009, 04:55: PM
Genetic drift is the accumulation of random events that change the makeup of a gene pool slightly, but often compound over time. It refers to the random fluctuations in the frequency of the appearance of a gene in a small isolated population, presumably owing to chance rather than natural selection. Accidents in small populations can change the frequency of some genes in a population, even if they give no survival advantage. Thus genetic drift provides diversity without any adaptations
