Someaclonal varitions appears in:

Options

A. Organism produced through somatic hybridization
B. plants growing in highly polluted conditions
C. Apomictic plants
D. Tissue culture raised plants

Answer

**Step-by-Step Solution:**

1. **Understanding Somaclonal Variation**:
- Somaclonal variations refer to the genetic variations that occur in plants that have been produced through tissue culture techniques. These variations arise from the somatic cells of the plant, which are non-reproductive cells.

2. **Identifying Soma Clones**:
- Soma clones are derived from somatic cells, which are any cells in the organism that are not germ cells (sperm or egg). When these somatic cells are cultured, they can produce clones that may exhibit variations due to mutations or epigenetic changes.

3. **Analyzing the Options**:
- **Option 1**: Organisms produced through somatic hybridization - This involves the fusion of somatic cells from different species, not related to somaclonal variation.
- **Option 2**: Plants growing in highly polluted conditions - Pollution does not directly cause somaclonal variation.
- **Option 3**: Apomictic plants - These reproduce asexually from ovules and do not relate to somaclonal variation.
- **Option 4**: Tissue culture raised plants - This is the correct option, as somaclonal variations are commonly observed in plants that are propagated through tissue culture.

4. **Conclusion**:
- The correct answer is that somaclonal variations appear in tissue culture raised plants.

**Final Answer**: Somaclonal variations appear in tissue culture raised plants.
