Solution

failed
failed

The answer is (C): It does not exchange genetic information with other species.

Explanation for each option:

(A) It does not share its habitat with related species.

  • Incorrect. While habitat isolation can contribute to reproductive isolation, it is not the sole basis. Species can be reproductively isolated even if they share habitats through mechanisms like temporal or behavioral isolation.

(B) It does not exist out of a single habitat.

  • Incorrect. A species can exist in multiple habitats and still be reproductively isolated from other species. Reproductive isolation is more about the inability to exchange genetic material rather than the number of habitats.

(C) It does not exchange genetic information with other species.

  • Correct. Reproductive isolation is defined by the inability of a species to exchange genetic information with other species, preventing gene flow and maintaining distinct species.

(D) It does not undergo evolutionary changes for a significant period of time.

  • Incorrect. Evolutionary stasis does not necessarily imply reproductive isolation. A species can undergo evolutionary changes and still remain reproductively isolated from others.

In summary, reproductive isolation is primarily about the lack of genetic exchange between species, making option (C) the correct answer.
