Sex chromatin present in `:-`

Options

A. Drum stick like in lobe of Neutrophil
B. Drum stick like in lobe of Basophil
C. Drum stick like in lobe of Eosinophil
D. Drum stick like in lobe of lymphocyte

Answer

**Step-by-Step Solution:**

1. **Understanding Sex Chromatin**:
- Sex chromatin refers to a densely staining mass found within the nucleus of undividing cells, specifically in normal female mammals. It is a form of heterochromatin that represents the inactivated X-chromosome.

2. **Identifying the Options**:
- The question provides four options regarding where sex chromatin is present:
1. Drumstick-like structure in the lobe of neutrophils
2. Drumstick-like structure in the lobe of basophils
3. Drumstick-like structure in the lobe of eosinophils
4. Drumstick-like structure in the lobe of lymphocytes

3. **Analyzing the Correct Option**:
- Among the options, sex chromatin is specifically associated with neutrophils in females. The "drumstick" appearance is a characteristic feature of the inactivated X-chromosome in female neutrophils.

4. **Conclusion**:
- Therefore, the correct answer is that sex chromatin is present in the drumstick-like structure in the lobe of neutrophils.

**Final Answer**: Sex chromatin is present in the drumstick-like structure in the lobe of neutrophils (Option 1).
