WebMicroevolution is a change in the frequency of gene variants, alleles, in a population, typically occurring over a relatively short time period. Population genetics is the field of biology that studies allele frequencies in populations and how they change over time. Allele frequency refers to how common an allele is in a population. WebThere 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. Each mechanism of evolution can be characterized by how it ...
