Abstract excerpt
Assortative mating, when individuals of similar phenotypes mate, likely plays a key role in preventing gene flow during speciation. Reinforcement occurs when two previously geographically separated (allopatric) groups meet after having evolved partial postzygotic isolation; they are selected to evolve or enhance assortative mating to prevent costly intergroup matings that produce only maladaptive or sterile...
