Question

Quizplus · Accepted Answer

The fact that two species of monkeyflowers have diverged in the structure of their flowers and can no longer be effectively pollinated by the same pollinator species suggests that they have developed different floral structures that prevent hybridization. This is an example of mechanical isolation, which is a type of reproductive isolation that occurs when differences in the physical structures of organisms prevent mating and fertilization between individuals of different species.
