Which Is Genetic Drift A Major Factor In Evolution Apex? The genetic drift is a major factor in evolution when there is lower gene flow and when there is no selective pressure and when there is a bottleneck in the environment. What is genetic drift in evolution? Genetic drift describes random fluctuations in the numbers
What Are The Effects Of Genetic Drift? Genetic drift can result in the loss of rare alleles, and can decrease the size of the gene pool. Genetic drift can also cause a new population to be genetically distinct from its original population, which has led to the hypothesis that genetic drift plays a role in
What Increases Random Genetic Drift? Genetic drift is a random process that can lead to large changes in populations over a short period of time. Random drift is caused by recurring small population sizes, severe reductions in population size called “bottlenecks” and founder events where a new population starts from a small number of individuals.
