A: The number of male gametes produces is always greater than the number of female gametes produced.
R: A large number of male gametes fail to reach upto the female gamete.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion
B. It both Assertion & Reason are true but the reason is not the correct explanation of the assertion
C. If Assertion is true statement but Reason is false
D. If both Assertion and Reason are false statements

Answer

To solve the assertion and reason question, we need to analyze both statements carefully.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that the number of male gametes produced is always greater than the number of female gametes produced.
- This is a biological fact. In many organisms, especially in animals, males produce a significantly higher number of sperm (male gametes) compared to the number of eggs (female gametes) produced by females.

2. **Understanding the Reason (R)**:
- The reason states that a large number of male gametes fail to reach the female gamete.
- This is also true. During the process of fertilization, many sperm do not reach the egg due to various factors such as the distance they must travel, the conditions of the reproductive tract, and competition among sperm.

3. **Connecting Assertion and Reason**:
- The reason explains why there is a higher production of male gametes. Since many male gametes do not successfully reach the female gamete, producing a larger number compensates for those that are lost.
- Therefore, the assertion is supported by the reason.

4. **Conclusion**:
- Both the assertion and reason are true, and the reason provides a correct explanation for the assertion.
- Thus, the correct answer is that both statements are true and the reason is the correct explanation for the assertion.

### Final Answer:
Both the assertion and reason are true, and the reason is the correct explanation for the assertion.
