B) fusion
C) allopatric speciation
D) reproductive isolation

Quizplus · Accepted Answer

Fusion is the process by which two distinct species become one due to weak reproductive barriers in the hybrid zone. This is seen among cichlids in Lake Victoria where species have interbred and fused into new hybrid species. Reinforcement would not occur in this situation as it involves strengthening of reproductive barriers, allopatric speciation occurs when populations are geographically separated, and reproductive isolation is a general term for any mechanism that prevents interbreeding.
