Find the odd one w.r.t somaclonal variations

Options

A. Produced during tissue culture
B. Some may be useful and stable
C. All are useful and very stable
D. Some of the significant variations have been taken up in plant breeding

Answer

To solve the question of finding the odd one with respect to somaclonal variations, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Somaclonal Variation**:
- Somaclonal variation refers to the genetic variation observed in plants that are produced through tissue culture. It arises due to genetic mutations that occur during the in vitro culture process.

2. **Analyze the Options**:
- We need to evaluate the statements provided in the options regarding somaclonal variations.
- The statements typically include:
a) Produced during tissue culture.
b) Some may be useful and stable.
c) All are useful and very stable.
d) Some significant variations have been utilized in plant breeding.

3. **Evaluate Each Statement**:
- **Option a**: "Produced during tissue culture" - This is true as somaclonal variations occur during the tissue culture process.
- **Option b**: "Some may be useful and stable" - This is also true as not all variations are beneficial; some may be useful while others may not.
- **Option c**: "All are useful and very stable" - This statement is false because not all somaclonal variations are useful or stable; many may be detrimental or unstable.
- **Option d**: "Some significant variations have been taken up in plant breeding" - This is true as some variations are indeed used to develop superior plant varieties.

4. **Identify the Odd One Out**:
- Since option c ("All are useful and very stable") is the only statement that is incorrect regarding somaclonal variations, it is the odd one out.

5. **Conclusion**:
- Therefore, the odd one with respect to somaclonal variations is option c.

### Final Answer:
The odd one with respect to somaclonal variations is **option c: All are useful and very stable**.
