If a butterfly has chromosome number 360 in its meiocyte (2n). What will be the chromosome number in its gametes ?

Options

A. 380
B. 180
C. 95
D. 760

Answer

To determine the chromosome number in the gametes of a butterfly with a meiocyte (2n) chromosome number of 360, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Chromosome Number in Meiocytes**:
- The meiocyte is the diploid cell (2n) that undergoes meiosis to form gametes. In this case, the butterfly has a meiocyte chromosome number of 360.

2. **Understand the Diploid and Haploid Relationship**:
- Diploid cells (2n) contain two sets of chromosomes, one from each parent. In contrast, haploid cells (n), such as gametes, contain only one set of chromosomes.

3. **Calculate the Chromosome Number in Gametes**:
- To find the chromosome number in the gametes, we need to divide the diploid number by 2.
- Therefore, the number of chromosomes in the gametes will be:
\[ n = \frac{2n}{2} = \frac{360}{2} = 180 \]

4. **Conclusion**:
- The chromosome number in the gametes of the butterfly is 180.

### Final Answer:
The chromosome number in the gametes of the butterfly is **180**.
