Five microevolutionary mechanisms
WebJan 21, 2024 · Causes of Microevolution. Microevolution refers to small and often subtle shifts in the genetic makeup of a population from one generation to the next. Because … 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.

WebIt takes place when an individual migrates between populations. The process causes an increase in the genetic diversity of a population. Natural selection – it can be artificial or natural and takes hundreds and thousands of years to take place and cause remarkable changes.
