WebIn the fields of ecology and evolutionary biology, allopatry is typically used to describe populations that are isolated to such a degree that dispersal and gene flow is reduced to negligible levels, such that populations are evolutionarily independent. Web8 Jun 2024 · Allopatric Speciation A geographically-continuous population has a gene pool that is relatively homogeneous. Gene flow, the movement of alleles across the range of the species, is relatively free because individuals can move and then mate with individuals in their new location.
