Which of the following shows the correct pairing of th organism and the number of chromosomes found in meiocyte ?

Options

A. Ophioglossum -630
B. Potato - 24
C. Maize - 20
D. Apple -17

Answer

To solve the question regarding the correct pairing of organisms and the number of chromosomes found in meiocytes, we will follow these steps:

### Step 1: Understand Meiocytes
Meiocytes are diploid cells that undergo meiosis to produce gametes. Therefore, the number of chromosomes in meiocytes is represented as 2n, where n is the haploid number.

### Step 2: Analyze the Options
We need to evaluate each organism and its corresponding chromosome number to determine if the number given is for meiocytes (2n).

1. **Ophioglossum**:
- Given: 630
- Actual diploid number: 1260 (haploid number = 630)
- Conclusion: Incorrect pairing.

2. **Potato**:
- Given: 24
- Actual diploid number: 48 (haploid number = 24)
- Conclusion: Incorrect pairing.

3. **Maize**:
- Given: 20
- Actual diploid number: 40 (haploid number = 20)
- Conclusion: Correct pairing.

4. **Apple**:
- Given: 17
- Actual diploid number: 34 (haploid number = 17)
- Conclusion: Incorrect pairing.

### Step 3: Identify the Correct Answer
From the analysis, we see that the only organism with the correct pairing of the organism and the number of chromosomes found in meiocyte is **Maize**.

### Final Answer:
The correct pairing of the organism and the number of chromosomes found in meiocyte is **Maize (20)**.
