Question

Assertion :Species are groups of potentially interbreeding natural populations that are isolated from other such groups. Reason: Reproductive isolation brings about distinctive morphological characters.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

Answer: (D)

• Species are groups of organisms with similar characters and capable of interbreeding among themselves. They are not necessarily isolated from other such groups (other species ) as except for autotrophic organisms, each species requires at least another species it can feed on.
• Reproductive isolation prevents members of one species to mate and produce offspring with another species. This rather prevents the bringing of distinctive morphological characters.

So, the correct answer is 'Both Assertion and Reason are incorrect'.
