Definitions:

Hybrid Sterility

A condition where offspring from the cross between two different species are infertile, preventing them from producing offspring.

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.
