ADVERTISEMENTS: ADVERTISEMENTS: A reproductive isolating mechanism is a structural, functional, or behavioural characteristic that prevents successful reproduction from occurring between different species. This occurs in two ways: (1) natural selection may directly generate reproductive isolating barriers such as habitat isolation, immigrant inviability, or extrinsic post-zygotic isolation; or (2) the force of natural selection may contribute to reproductive Reproductive isolation is maintained due to lack of hybrid survival/reproduction. Geographic isolation and reproductive isolation are two mechanisms that lead to speciation.Speciation refers to the formation of a new, distinct species from the main population of a particular organism mainly due to genetic incompatibility. what prevents members of different species from successfully interbreeding?

Having said this, it must be admitted that it is no longer possible to follow Mayr's concept as definitive. Reproductive isolation definition is - the inability of a species to breed successfully with related species due to geographical, behavioral, physiological, or genetic barriers or differences. Reproductive isolation can occur in a variety of ways reproductive isolation = means of preventing gene flow between two species for a new species to evolve from an existing (sexually reproducing) species, there must be a reproductive isolating mechanism in place reproductive isolating mechanisms can be classified as either prezygotic or postzygotic Reproductive isolation is unique in evolution because it is not a trait possessed by members of a single species, but a composite character that is the joint property of a pair of species.
