Title: Re: What is genetic drift? Under what circumstances do you expect genetic drift to o Post by: duddy on Feb 1, 2012 Genetic drift is the change in allelic frequencies as a consequence of random processes. Genetic drift is expected to occur in small populations and is unlikely to be important in large populations. Genetic drift tends to decrease genetic variation.
