IPA: /ˌæl.əˈpætrɪk/
KK: /ˌæl.əˈpæ.trɪk/
Describing species or populations that live in different geographic areas and do not overlap, often leading to them being unable to interbreed due to this separation.
The allopatric populations of the species evolved distinct characteristics due to their geographic isolation.
Allopatric is formed from "allo-" (from Greek "allos", meaning other) and "patria" (from Greek "patria", meaning homeland or fatherland). The term describes species that are geographically separated, hence having different homelands.
Think of 'other' ('allo-') homelands ('patria') to remember that 'allopatric' refers to species that are separated by geography.
