In a blood sample a WBC has a nucleus with drum-stick. This indicates that the blood sample has come from a person who is

Options

A. Haemophilic
B. Diabetic
C. Female
D. Sickle cell-anaemic

Answer

To solve the question regarding the identification of a blood sample with a WBC nucleus that has a drumstick appearance, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Drumstick Appearance**:
- The "drumstick" appearance refers to a specific morphological feature observed in the nuclei of certain white blood cells (WBCs), particularly in females. This feature is associated with the presence of Barr bodies.

2. **Identifying Barr Bodies**:
- Barr bodies are inactivated X chromosomes found in females. In a typical female (XX), one of the X chromosomes condenses and forms a Barr body, which can appear as a drumstick-like structure when viewed under a microscope.

3. **Analyzing the Options**:
- The question provides four options: hemophilic, diabetic, female, or sickle cell anemia.
- Hemophilia and diabetes are conditions that do not specifically relate to the presence of a drumstick appearance in WBCs.
- Sickle cell anemia is also a genetic disorder that does not involve the drumstick appearance of WBC nuclei.

4. **Conclusion**:
- Since the drumstick appearance is indicative of Barr bodies, which are present in females, the correct answer to the question is that the blood sample has come from a person who is **female**.

### Final Answer:
- The blood sample has come from a person who is **female**.
