Mechanism preventing interbreeding is called – (1) Adaptation (2) Isolation (3) Reproduction (4) Recombination

1 Answer

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 and biology developed to prevent interbreeding between species. The specific term is Reproductive Isolation, which acts to prevent some, any, or all stages of reproduction from occurring. Reproductive Isolation is very important in keeping animal species separated.
