Microevolution: Definition, Examples, Quiz Biology …

Microevolution is the change in allele frequencies that occurs over time within a population. This change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic drift. This change happens over a relatively short (in evolutionary terms) amount of time compared to the changes termed macroevolution. WebMar 4, 2011 · There are five forces which play major roles in contributing to such genetic variations. They include mutation, natural selection, gene flow, genetic drift, and non random mating. In terms of fitness, only natural selection strives to make the individual more fit to the environment. Mutation. immanuel baptist church paragould ar
