As- Inheritance of Kappa particles in Paramecium is type of extra-nuclear inheritance. R- The above process is also called Cytoplasmic inheritance.

Options

A. If both As and R are correct and R is correct explanation of As
B. If both As and R are correct but R is not correct explanation of As
C. If As is correct, R is wrong
D. If both As and R are wrong.

Answer

To solve the question regarding the inheritance of Kappa particles in Paramecium, we will analyze both the assertion and the reason step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that the inheritance of Kappa particles in Paramecium is a type of extra-nuclear inheritance.
- Extra-nuclear inheritance refers to the transmission of genetic material that occurs outside the nucleus, typically involving organelles like mitochondria or plastids, or in this case, Kappa particles.

2. **Understanding Kappa Particles**:
- Kappa particles are symbiotic bacteria found in Paramecium that can influence the phenotype of the organism. They are not located in the nucleus but in the cytoplasm, which is crucial for understanding their inheritance pattern.

3. **Understanding the Reason**:
- The reason states that this process is also called cytoplasmic inheritance.
- Cytoplasmic inheritance is indeed a form of extra-nuclear inheritance where genetic information is passed through the cytoplasm, often via organelles or other cytoplasmic elements.

4. **Connecting Assertion and Reason**:
- Since Kappa particles are inherited through the cytoplasm and not the nucleus, the assertion is correct.
- The reason correctly identifies that this type of inheritance is also known as cytoplasmic inheritance, which supports the assertion.

5. **Conclusion**:
- Both the assertion and the reason are correct, and the reason provides a valid explanation for the assertion. Therefore, the correct answer is that both the assertion and reason are true, and the reason explains the assertion.

### Final Answer:
Both the assertion and reason are correct, and the reason is the correct explanation of the assertion.
