11.3 Other Mechanisms of Evolution KEY CONCEPT Natural selection is not the only mechanism through which populations evolve.
THE FIVE FACTORS OF EVOLUTION. 1. Genetic drift is a change in allele frequencies due to chance. Genetic drift causes a loss of genetic diversity.
Mutation & genetic drift
Evolution of Populations. A. Genetic drift is a change in allele frequencies due to chance. Genetic drift causes a loss of genetic diversity. It is most.
Selection causes Microevolution Frequency of alleles (versions of a gene) changes in a population.
