Assertion A: Most humans pass accurate genetic instructions from one generation to the next.
Reason R: In spite of high mutation rate, the sequence of the human genome changes by only a few nucleotides during division.
Reason R: In spite of high mutation rate, the sequence of the human genome changes by only a few nucleotides during division.
Show Hint
- Both A and R are true and R is the correct explanation of A
- Both A and R are true and R is NOT the correct explanation of A
- A is true but R is false
- A is false but R is true
The Correct Option is C
Solution and Explanation
Step 1: Evaluation of Assertion
Assertion A is true: Genetic inheritance is remarkably high-fidelity, ensuring the survival of species.
Step 2: Evaluation of Reason
Reason R claims there is a "high mutation rate." This is factually incorrect. DNA replication has extremely high fidelity (accuracy) due to proofreading and repair mechanisms, leading to a very low mutation rate.
Step 3: Reasoning
Because the mutation rate is actually very low (not high), the genome remains stable. Reason R contains a false premise.
Step 4: Conclusion
A is true but R is false. Final Answer: (C)
