Question

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : Hardy-Weinberg equilibrium assumes no mutation, migration or selection.
Reason (R) : Hardy-Weinberg law describes changes in gene frequency across generations. In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A).
• B. Both (A) and (R) are correct but (R) is NOT the correct explanation of (A).
• C. (A) is correct but (R) is incorrect.
• D. (A) is incorrect but (R) is correct.

Hint:

Hardy-Weinberg = No evolution → Gene frequency stays constant

Answer 1

The Correct Option is C

Concept:
Hardy-Weinberg equilibrium describes a condition where allele frequencies remain constant across generations under specific assumptions.

Step 1: Understanding Assertion (A)

• Hardy-Weinberg equilibrium assumes:
• No mutation
• No migration
• No natural selection
• Large population size
• Random mating Thus, Assertion is correct.

Step 2: Understanding Reason (R)

• Hardy-Weinberg principle actually states:
• Gene frequency remains constant (no change)
• It does not describe change, but stability Thus, Reason is incorrect.

Step 3: Logical Analysis

• Assertion is true
• Reason is false Final Conclusion: \[ \boxed{\text{Option (C)}} \]
