Answer:
The correct answer is "interbreeding".
Explanation:
In biology, interbreeding is defined as the reproduction of two members of different races or species. The interbreeding concept is closely related to the concept of biological species, since a characteristic of a biological species is that it should be able to reproduce. Organisms that are reproductively isolated, have the potential of interbreeding with other races or species, which could potentially result in the creation of a new species or race.
