Native English speakers, which is the term in English to refer to the fact that different species....?

Question

are not able to mate with each other?

In my native language, it is "reproductive isolation", in literal terms. Does this term make sense in English?

Answer 1

"Reproductive isolation" in English refers to different populations of the SAME species not interbreeding.

We don't have a term to refer to non-breeding between different species.  There's no need for one.  Non-breeding with others is inherent in the definition of "species."  (There're exceptions to this generalization, of course.  The quagga and the brown zebra interbred freely -- making some question whether the quagga was really a species, or just a variety of brown zebra).

Answer 2

Yes, the term "reproductive isolation" gives 169,000 hits on google, and seems to always refer to the same meaning.  I suspect this was a term coined by a scientist which has been literally translated into other languages.
