Answer:
The two populations might become separate species
Explanation:
Allopatric speciation is one of the mechanisms that can lead to the establishment of a new species of organisms as a result of geographical separation of different population of organisms of the same species.
<em>When organisms of the same species are geographically separated, this prevents gene flow between the two populations and each population develops various adaptive features in order to cope with their environments. Thus, each population might end up becoming a new species.</em>
