Suppose that two populations that were once isolated come into contact.Which result would not be likely?
A) Little reinforcement of prezygotic barriers if the hybrids are unfit
B) Interbreeding between the two populations if reproductive isolation is not complete
C) Spread of hybrids through both populations if the hybrids are fit, resulting in gene flow between them
D) A lack of interbreeding if reproductive isolation had been established before contact
E) The development of hybrid zones that last for long periods of time

Reinforcement of prezygotic barriers is more likely if hybrids are unfit because natural selection would favor mechanisms that prevent the production of unfit offspring, thus strengthening reproductive isolation between the populations.
