Question

Bugs feeding on two different host plants is an example of which type of pre-zygotic isolation?

A. Gametic

B. Morphological

C. Temporal

D. Habitat (ecological)

Answer 1

Bugs feeding on two different host plants and they can't interbreed because individuals like to mate in their preferred habitat, and they do not meet individuals of other species with different ecological habitat.

On the other hand, in Gametic isolation the egg and sperm are released and fused but zygote is not formed.

In the temporal isolation the timing of mating is different in two species.

And in morphological isolation morphological differences prevent the mating between two species.

So the correct answer is (D) Habitat (ecological)
