Sympatric populations are those that share the same geographical area, making it easier for individuals from different species to interact and potentially mate. Therefore, selection should favor reinforcement of reproductive isolation among related species in sympatric populations over allopatric populations, where individuals from different species are separated by geographical barriers and have less opportunity to interact and mate. Peripatric populations are those that are geographically isolated, but with a small founder population entering a new area, and would not necessarily have a stronger selection for reinforcement of reproductive isolation among related species compared to sympatric populations.
