Where are barr bodies found ?

Options

A. Ova
B. sperms
C. somatic cells of man
D. somatic cells of woman

Answer

### Step-by-Step Solution:

1. **Understanding Barr Bodies**:
- Barr bodies are structures formed by the inactivation of one of the X chromosomes in females. This process is known as X-inactivation or Lyonization.

2. **Identifying Where Barr Bodies Are Found**:
- Barr bodies are specifically found in the somatic cells of females. Females have two X chromosomes (XX), and during development, one of these X chromosomes in each cell is randomly inactivated, leading to the formation of a Barr body.

3. **Excluding Other Options**:
- **Ova**: Barr bodies are not found in ova (egg cells) because they are not somatic cells and the X chromosome in ova is not inactivated.
- **Sperms**: Sperm cells contain either an X or a Y chromosome, but they do not have Barr bodies since they do not have two X chromosomes to inactivate.
- **Somatic Cells of Men**: Males have one X and one Y chromosome (XY), so they do not have Barr bodies since there is no second X chromosome to inactivate.

4. **Conclusion**:
- The only correct answer is that Barr bodies are found in the somatic cells of women.

### Final Answer:
Barr bodies are found in the somatic cells of women.
