Is gene flow the most important evolutionary force in plants?

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. WebThe environment may impose an external barrier to reproduction, such as a river or mountain range, between two incipient species but that external barrier alone will not make them separate, full-fledged species. Allopatry may start the process off, but the evolution of internal (i.e., genetically-based) barriers to gene flow is necessary for speciation to be …
