the condition of existing in areas that are geographically separated from one another;esp the condition of genetically similar species which cannot interbreed because of this geographical separation

This gene exchange may have occurred either sporadically between periods of allopatry, or regularlythroughout the divergence process.

However, the fact that species divergence correlates with island size emphasizes the importance of geographic isolation (allopatry) in speciation.

In allopatry, results suggest habitat selection: dilectus preferring grasslands with little bare soil while bechuanae occurring in open shrublands.
