What would be the number of chromosomes in the meiocyte any gamete of onion respectively ?

Options

A. 24, 12
B. 34, 17
C. 16, 8
D. 14, 17

Answer

To solve the question about the number of chromosomes in the meiocyte and gamete of onion, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- A meiocyte is a cell that undergoes meiosis to produce gametes.
- Gametes are the reproductive cells (sperm and egg) that are haploid (n).

2. **Identify the Diploid Number**:
- In onions, the diploid number (2n) of chromosomes is known to be 16. This means that in the meiocyte, which is diploid, there are 16 chromosomes.

3. **Determine the Haploid Number**:
- After meiosis, the diploid meiocyte (2n) divides to form haploid gametes (n).
- To find the haploid number, we divide the diploid number by 2.
- Therefore, if 2n = 16, then n = 16/2 = 8.

4. **Conclusion**:
- The number of chromosomes in the meiocyte of onion is 16, and the number of chromosomes in the gametes is 8.

5. **Final Answer**:
- The respective numbers of chromosomes in the meiocyte and gamete of onion are 16 and 8.

### Answer:
The number of chromosomes in the meiocyte and gamete of onion is 16 and 8, respectively.
