Detailed explanation-1: -There are five key mechanisms that cause a population, a group of interacting organisms of a single species, to exhibit a change in allele frequency from one generation to the next. These are evolution by: mutation, genetic drift, gene flow, non-random mating, and natural selection.

Detailed explanation-2: -They are: mutation, non-random mating, gene flow, finite population size (genetic drift), and natural selection.

Detailed explanation-3: -These factors are the “forces of evolution.” There are four such forces: mutation, gene flow, genetic drift, and natural selection.

Detailed explanation-4: -Factors of Genetic Diversity Genetic diversity is influenced by four events controlling evolution: mutation, genetic drift, gene flow, and natural selection. However, only mutations can produce completely new alleles.
