Question

Secondary contact can lead to further evolution of reproductive isolating mechanisms (a process known as secondary reinforcement) when: a. divergence that evolved during allopatry put hybrid offspring at a selective disadvantage after secondary contact b. divergence that evolved during sympatry put hybrid offspring at a selective disadvantage after secondary contact c. divergence that evolved during allopatry put hybrid offspring at a selective advantage after secondary contact d. divergence that evolved during sympatry put hybrid offspring at a selective advantage after secondary contact e. post-zygotic reproductive isolating mechanisms that evolved during allopatry put hybrid offspring at a selective advantage after secondary contact f. pre-zygotic reproductive isolating mechanisms that evolved during allopatry put hybrid offspring at a selective advantage after secondary contact

Explanation / Answer

Reinforcement is the process by which natural selection increases reproductive isolation but reduces the fitness of the hydrids. So it occurs when the divergence evolve during alloparty put hybrid offspring at selective disadvantage after secondary contact
