Genetic Drift
Genetic Drift refers to the random fluctuations in the frequency of alleles, or alternative forms of genes, within a population over time. This phenomenon can lead to significant changes in the genetic composition of a population and is a fundamental concept in population genetics. It is influenced by several factors, including finite population size, genetic bottlenecks, and founder effects. In the context of gene flow, genetic drift can counteract the homogenizing effect of gene migration between populations, contributing to the maintenance of genetic diversity within and among populations. Genetic Drift sheds light on how populations evolve and adapt over time, providing valuable insights into evolutionary biology and genetics.
