Description : Mechanism preventing interbreeding is called – (1) Adaptation (2) Isolation (3) Reproduction (4) Recombination
Last Answer : (2) Isolation Explanation: Because interbreeding can destroy the genetic integrity of a species, causing it to become progressively infertile or extinct, evolutionary changes in anatomy ... reproduction from occurring. Reproductive Isolation is very important in keeping animal species separated.
