Grasshopper is an example of type of sex determination

Options

A. XO
B. XX
C. ZZ
D. ZO

Answer

### Step-by-Step Solution:

1. **Understanding Sex Determination**:
- Sex determination refers to the biological system that determines the development of sexual characteristics in an organism. Different organisms have different systems of sex determination.

2. **Identifying Grasshopper's Sex Determination System**:
- In grasshoppers, the sex determination system is classified as XO type. This means that males have only one X chromosome and no Y chromosome.

3. **Males and Females in Grasshoppers**:
- In male grasshoppers, the genotype is represented as X0 (where '0' indicates the absence of a second sex chromosome).
- In female grasshoppers, the genotype is XX, meaning they have a pair of X chromosomes.

4. **Comparison with Other Organisms**:
- To clarify, in humans, the sex determination system is XY, where males have one X and one Y chromosome (XY) and females have two X chromosomes (XX). This is different from the XO system found in grasshoppers.

5. **Conclusion**:
- Therefore, grasshoppers are an example of the XO type of sex determination, where males have one X chromosome and females have two X chromosomes.

### Final Answer:
Grasshopper is an example of XO type of sex determination.
