Is gene flow evolution
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 … WebBoth gene flow and genetic drift are evolutionary mechanisms (along with natural selection), they can produce changes in an allele frequency. However, gene flow can counteract the effects of the other two, as it tends to increase the genetic variation in a population and decrease the genetic differences between populations.
