Male frogs give calls that attract female frogs to approach and mate.Researchers examined mating calls of closely related tree frogs in South America.What outcomes can occur where the ranges of two species overlap?

Question

Quizplus · Accepted Answer

When the ranges of two closely related species overlap, there are multiple potential outcomes. Interspecific mating can occur, leading to hybridization and eventually fusion over time (option A). Alternatively, a stable hybrid zone can form if the hybrids are more adapted to the area of overlap than either parent species (option B). However, if the species are not successful in interbreeding, they may continue to diverge and become isolated by behavioral or genetic mechanisms (option C). Therefore, all of the listed outcomes are possible (option D). Option E, none of the above being possible, is not accurate as multiple potential outcomes are possible when species ranges overlap.
