Somaclonal variations 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 variation refers to the genetic variation that occurs in plants that are produced through tissue culture techniques. This variation arises due to changes in the genetic makeup of the cells during the tissue culture process.

2. **Identifying the Context**: The question asks where somaclonal variations appear. It is important to note that these variations are typically observed in plants that have undergone tissue culture.

3. **Analyzing the Options**:
- **Option 1: Somatic hybridization** - This involves the fusion of somatic cells from different species, which does not inherently lead to somaclonal variation.
- **Option 2: Plants in highly polluted conditions** - While these plants may exhibit changes due to environmental stress, such variations are often non-heritable and do not qualify as somaclonal variations.
- **Option 3: Apomictic plants** - Apomixis is a form of asexual reproduction that produces clones, thus not leading to variations.
- **Option 4: Tissue cultured plants** - This option is correct as somaclonal variations are specifically associated with plants that are grown from tissue culture.

4. **Conclusion**: Based on the analysis of the options, somaclonal variations appear in tissue cultured plants.

**Final Answer**: Somaclonal variations appear in tissue cultured plants.
