Match the following.

• Reinforcement

• reproductive barriers are weakened

• Fusion

• reproductive barriers are strengthened

• Sympatric Speciation

• continued production of hybrid individuals when they have similar fitness to their parent species and are able to survive and reproduce

• Allopatric Speciation

• population forms new species due to geographical isolation

• Stability

• population forms new species without geographical isolation
