Does reproductive isolation prevent gene flow
WebThe evolution of reproductive isolation is of central interest in evolutionary biology. In plants, this is typically achieved by a combination of pre- and postpollination mechanisms that prevent, or limit, the amount of interspecific gene flow. WebDec 31, 2024 · The mechanism for reproductive isolation is that gene flow is prevented. That is, the members from different populations do not exchange genes over many …

Webgene flow, also called gene migration, the introduction of genetic material (by interbreeding) from one population of a species to another, thereby changing the composition of the gene pool of the receiving population. The introduction of new alleles through gene flow increases variability within the population and makes possible new … WebReproductive isolation mechanisms prevent gene flow between different species and limit the development of hybrids, the offspring of two different species.
