Find out the wrong pair with respect to the number of chromosomes in meiocytes.

Options

A. Fruit fly - 8
B. Apple - 36
C. Rice - 24
D. Housefly - 12

Answer

To find the wrong pair with respect to the number of chromosomes in meiocytes, we need to analyze the given options one by one. Meiocytes are haploid cells formed as a result of meiosis, which is a reductional division occurring in diploid organisms.

### Step-by-Step Solution:

1. **Understanding Meiocytes**:
- Meiocytes are haploid cells produced after meiosis.
- Meiosis reduces the chromosome number by half, resulting in four haploid cells from one diploid cell.

2. **Analyzing the Options**:
- **Option 1: Fruit Fly (Drosophila melanogaster)** - It is known that fruit flies have 8 chromosomes in total (4 pairs). This statement is correct.
- **Option 2: Apple (Malus domestica)** - The statement claims apples have 36 chromosomes. However, apples actually have 34 chromosomes (17 pairs). This statement is incorrect.
- **Option 3: Rice (Oryza sativa)** - Rice has 24 chromosomes (12 pairs). This statement is correct.
- **Option 4: Housefly (Musca domestica)** - Houseflies have 12 chromosomes (6 pairs). This statement is also correct.

3. **Identifying the Wrong Pair**:
- From the analysis, the only incorrect statement is regarding apples, which are stated to have 36 chromosomes, whereas they actually have 34 chromosomes.

4. **Conclusion**:
- The wrong pair with respect to the number of chromosomes in meiocytes is the one related to apples, which incorrectly states that they have 36 chromosomes.

### Final Answer:
The wrong pair is: **Apple - 36 chromosomes** (correct number is 34 chromosomes).
