A : In spermatogenesis the first haploid forms are spermatids.
R : All the end of meiosis cells have haploid set of chromosomes

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion then mark (1)
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion then mark (2)
C. If Assertion is false statement but Reason is true then mark (3)
D. If both Assertion and Reason are false statement then Mark (4)

Answer

**Step-by-Step Solution:**

1. **Understanding Spermatogenesis**:
- Spermatogenesis is the process by which male germ cells develop into sperm. It involves several stages of cell division and differentiation.

2. **Identifying the Assertion**:
- The assertion states that "in spermatogenesis the first haploid forms are spermatids."
- We need to evaluate whether this statement is true or false.

3. **Meiosis and Haploid Cells**:
- Meiosis is a type of cell division that reduces the chromosome number by half, resulting in haploid cells.
- In spermatogenesis, the process begins with diploid spermatogonia, which undergo mitosis to form primary spermatocytes.

4. **First Meiotic Division**:
- The primary spermatocyte (diploid) undergoes the first meiotic division to produce two secondary spermatocytes, which are haploid (n).
- Therefore, the first haploid forms in spermatogenesis are actually the secondary spermatocytes, not the spermatids.

5. **Identifying the Reason**:
- The reason states that "at the end of meiosis, cells have a haploid set of chromosomes."
- This statement is true, as meiosis results in the formation of haploid cells.

6. **Conclusion**:
- Since the assertion is false (the first haploid forms are secondary spermatocytes, not spermatids), and the reason is true (meiosis results in haploid cells), we conclude that the correct relationship is that the assertion is false while the reason is true.

7. **Final Answer**:
- The correct option is that the assertion is false and the reason is true.
