The number of chromosome in meiocyte of butterfly is

Options

A. 1260
B. 20
C. 380
D. 8

Answer

To determine the number of chromosomes in the meiocyte of a butterfly, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terminology**:
- A meiocyte is a type of cell that undergoes meiosis to form gametes.
- Gametes are haploid cells, meaning they contain a single set of chromosomes (n).
- Meiocytes are diploid cells, meaning they contain two sets of chromosomes (2n).

2. **Identify the Number of Chromosomes in Gametes**:
- According to the information provided, the number of chromosomes in the gametes of the butterfly is given as 190.
- This means that the haploid number (n) is 190.

3. **Calculate the Number of Chromosomes in Meiocyte**:
- Since meiocytes are diploid, the number of chromosomes in a meiocyte is double that of a gamete.
- Therefore, we can calculate the diploid number (2n) as follows:
\[ 2n = 2 \times 190 = 380 \]

4. **Conclusion**:
- The number of chromosomes in the meiocyte of a butterfly is 380.

### Final Answer:
The number of chromosomes in the meiocyte of a butterfly is **380**.
