Two species of flies, drosophila melanogaster and drosophila simulans, can mate. they usually do not mate, however, even if they are kept together in a laboratory. males court the females of both species, but the females prefer to mate with males of their own species. which isolating mechanism does this describe? behavioral temporal artificial anatomical

The right option is; behavioral

This describes behavioral isolating mechanism.

Behavioral isolation is a type of reproductive isolation that occurs when two closely related species that are capable of mating, do not mate because of differences in their behavior in terms of courtship rituals and signals. Under behavioral isolation, organisms choose and mate only with members of their own species. Every group of organisms has its own specific courtship rituals or signals that help them to choose the right mating partner.
