Question

Given below are two statements related to sympatric speciation:
Statement (I): Formation of species within single population without geographical isolation is sympatric speciation.
Statement (II): Migration of individuals is helpful in sympatric speciation.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

Sympatric speciation occurs without geographical isolation, and migration causes gene flow that opposes isolation.

Answer 1

The Correct Option is C

Step 1: Statement (I)
In sympatric speciation, a new species forms within a single population living in the same area without geographical isolation, for example through polyploidy. So Statement (I) is correct.

Step 2: Statement (II)
Migration brings gene flow and mixes gene pools. This works against the reproductive isolation needed for speciation, so Statement (II) is incorrect.

Step 3: Conclusion
Statement (I) is correct but Statement (II) is incorrect.

Final Answer:
Statement (I) is correct and Statement (II) is incorrect. \[ \boxed{\text{(C) }\text{Statement (I) is correct but Statement (II) is incorrect.}} \]
