The document describes a scenario where two populations of beetles have incompatible reproductive organs, highlighting an example of mechanical isolation. This incompatibility prevents mating and fertilization, illustrating the concept of pre-zygotic isolation. The options provided include post-zygotic isolation, zygote mortality, and temporal isolation, but the correct answer relates specifically to mechanical and pre-zygotic isolation.
