Allopatric speciation refers to speciation that occurs because populations have become geographically isolated from one another.
Explanation:
Allopatric speciation refers to speciation that occurs because populations have become geographically isolated from one another. Over time, the populations may become genetically distinct because gene flow between the two stops. Genetic drift and natural selection operate independently in each population and mutations arise in each population.
Allopatric speciation is regarded as the main process by which new species arise. Over time, the two populations accumulate enough differences so that they are incapable of interbreeding if they were ever to come into contact with one another again.
