Question

Quizplus · Accepted Answer

This is an example of behavioral isolation because the females of D. pseudoobscura have a preference for the courtship signals of their own species and are less responsive to the courtship signals of a closely related species, D. persimilis. This behavioral difference leads to reduced interbreeding and reproductive isolation between the two species.
