AIIMS 2014 Botany Speciation MCQ Question
Assertion Reproductive isolation brings about sympatric speciation. Reason It is the primary mode of speciation. e.g., Darwin’s finches.
Both Assertion and Reason are true and Reason is the correct explanation of Assertion
Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion
Assertion is true but Reason is false
Both Assertion and Reason are false
Correct Answer
Detailed Explanation
The assertion is true because reproductive isolation is indeed a key mechanism that can lead to sympatric speciation, where new species evolve from a common ancestor while living in the same geographic area. However, the reason is misleading; while reproductive isolation is important, it is not the primary mode of speciation overall, as allopatric speciation (which involves geographic separation) is often more common. Therefore, both statements are true, but the reason does not adequately explain the assertion.
