Male frogs give calls that attract female frogs to approach and mate.Researchers examined mating calls of closely related tree frogs in South America.If reinforcement of postzygotic isolation is occurring,what would you expect if you compare the calls of the two species in zones of sympatry versus zones of allopatry?

Question

Quizplus · Accepted Answer

If reinforcement of postzygotic isolation is occurring, we would expect to see more differences in the mating calls of the two species in areas of sympatry where they overlap, as this would help to prevent hybridization and ensure mating only occurs between individuals of the same species. Therefore, the calls would be more different in areas of sympatry compared to areas of allopatry.
