In what way the murky waters of Lake Victoria might be contributing to the decline in cichlid species and also how it is affecting the formation of new species. Concept introduction: The hybrid zone is an overlapping region where the two different species mate and reproduce offspring (hybrid). There can be three outcomes of a hybrid zone, namely reinforcement, fusion and stability. The fusion occurs when the reproductive barriers are not strong between the two species. As a result, gene flow occurs greatly between two species leading to their fusion into one species. It is the reverse of speciation.
