Which chromosome set is found in male Grasshopper?

Options

A. XX
B. YY
C. X
D. XY

Answer

To determine the chromosome set found in male grasshoppers, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Sex Determination System**: Grasshoppers use the XO sex determination system. In this system, males have only one X chromosome and no corresponding Y chromosome.

2. **Identify Chromosome Sets**:
- **Females**: In grasshoppers, females have two X chromosomes (XX). This makes them homogametic, meaning they produce gametes that are the same (both carry an X chromosome).
- **Males**: Males have one X chromosome and no other chromosome (O). This makes them heterogametic, as they can produce two types of gametes: one carrying the X chromosome and one that lacks it.

3. **Analyze the Options**:
- The options provided are XX, YY, X0, and XY.
- **XX**: This is incorrect as it represents the female chromosome set.
- **YY**: This does not exist in grasshoppers.
- **X0**: This is correct as it represents the male chromosome set (one X and no other chromosome).
- **XY**: This is incorrect as grasshoppers do not have a Y chromosome.

4. **Conclusion**: The correct chromosome set found in male grasshoppers is X0.

### Final Answer:
The chromosome set found in male grasshoppers is **X0**.
