The gray tree frog is closely related to the green tree frog genetically, but they have different mating calls. This suggests that speciation occurred because of reproductive isolation.
Explanation:
It is a speciation that occurs due to a type of reproductive isolation. The song of each of these frogs has specific patterns only recognizable by members of the same species, so they are called a mechanism of reproductive isolation.
Different courtship rituals in animal species create extremely potent reproductive barriers, which keep the two frog species isolated despite They are genetically close
