Question

Statement I: Absence of gene exchange between populations is called reproductive isolation.
Statement II: Natural selection is the driving force of evolution.

• A. Both statements I and II are true
• B. Both statements I and II are false
• C. Statement I is true, but Statement II is false
• D. Statement I is false, but Statement II is true

Hint:

Reproductive isolation leads to speciation, while natural selection drives evolution by favoring advantageous traits.

Answer 1

The Correct Option is A

Step 1: Understanding Reproductive Isolation
- Reproductive isolation prevents gene flow between populations, leading to speciation.
- This process is fundamental in evolutionary biology. Step 2: Role of Natural Selection in Evolution
- Natural selection drives evolution by favoring traits that enhance survival and reproduction.
- It leads to adaptation and speciation over time. Step 3: Conclusion
Both statements correctly describe key evolutionary principles, making Option (1) correct.
