Question

Two species of frogs are unable to mate with each other because they have different mating calls. This is an example of

A) genetic drift
B) geographic isolation
C) none of these
D) reproductive isolation

Answer 1

The answer is D- reproductive isolation.

Answer 2

This is an example of reproductive isolation (behavioral).

Reproductive isolation is the situation where a species is unable to mate or breed successfully with a closely related species due to reproductive isolating barriers/differences which may be behavioral, geographical, mechanical or genetic. From the question, the different mating calls of the two species of frogs that prevents them from mating with each other is a powerful reproductive barrier called behavioral isolation. It prevents closely related species from interbreeding because they do not understand sexual clues given by another species.
