Electrofusion or chemofusion is used for -

Options

A. Cloning
B. Mutations
C. Protoplast fusion
D. Eugenics

Answer

**Step-by-Step Solution:**

1. **Understanding Electrofusion and Chemofusion**: Electrofusion and chemofusion are techniques used in biotechnology. They involve the fusion of cells or protoplasts (the living part of a plant or bacterial cell) using electrical or chemical methods.

2. **Identifying the Purpose**: The primary purpose of these techniques is to create hybrids or to induce mutations. This can lead to the development of new traits in organisms, which is particularly useful in agriculture and research.

3. **Analyzing the Options**:
- **Cloning**: This involves creating a genetically identical copy of an organism, which is not the primary function of electrofusion or chemofusion.
- **Mutation**: This refers to changes in the genetic material, which can be induced by high voltage in electrofusion.
- **Protoplast Fusion**: This is a specific application of electrofusion where protoplasts from different species are fused to create hybrid cells.
- **Eugenics**: This is a broader concept related to improving genetic qualities in humans, animals, or plants, but not directly related to electrofusion or chemofusion.
- **Fusionol**: This term does not relate to the context of electrofusion or chemofusion.

4. **Conclusion**: Based on the analysis, the correct answer is that electrofusion or chemofusion is primarily used for inducing **mutations**.

**Final Answer**: Electrofusion or chemofusion is used for **mutation**.
