Postzygotic Barrier

One of several reproductive isolating mechanisms that prevent gene flow between species after fertilization has taken place (e.g., hybrid inviability, hybrid sterility, and hybrid breakdown). Compare with prezygotic barrier.

Interbreeding

The mating of organisms within the same species, which can lead to the sharing of genetic traits and increased genetic similarity.

Habitat Isolation

A form of reproductive isolation where different species live in different habitats and do not meet, thus preventing mating.

Mechanical Isolation

A form of reproductive isolation where physical differences in the reproductive organs of different species prevent interbreeding.
