Question

Quizplus · Accepted Answer

In a hybrid zone, there can be interbreeding between two species that would result in the fusion of the two species, leading to a loss of the genetic and morphological differences between the two species. This occurs when the reproductive barrier between the two species is weak or absent, as seen in the cichlids in Lake Victoria. Allopatric speciation refers to the formation of new species due to geographic isolation, reproductive isolation refers to mechanisms that prevent interbreeding between two distinct species, and reinforcement is a process where natural selection strengthens reproductive barriers between two hybridizing species to maintain their genetic and phenotypic differences.
