Answer 1

If the members of two different populations do not interbreed due to difference in the structure of reproductive organs, then it is called mechanical isolation.

Explanation:

When differences in the size or shape of reproductive organs prevent copulation between populations, this is called mechanical isolation, a prezygotic reproductive isolating mechanism.
