When gene flow within a population is ended, it means that there is no more exchange of genetic material between individuals in that population and it can lead to reproductive isolation. Reproductive isolation can eventually lead to speciation (the formation of new species) over long periods of time, but in the immediate future, the most likely outcome is that the population will become genetically differentiated from other populations and develop barriers to interbreeding, such as behavioral or anatomical differences. This can create distinct populations within the same species with different gene frequencies and increased competition for resources. However, without new variations entering the population through gene flow, the potential for adaptation to changing environmental conditions may be limited.
