Assertion : Genes are responsible for transfer of characters from the parents to the offspring
Reason : Genes are present in the nucleus .

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false

Answer

To analyze the assertion and reason provided in the question, we can break it down into a step-by-step solution:

### Step 1: Understand the Assertion
- The assertion states that "Genes are responsible for the transfer of characters from the parents to the offspring."
- This means that genes, which are segments of DNA, carry the information necessary for inherited traits from one generation to the next.

### Step 2: Understand the Reason
- The reason states that "Genes are present in the nucleus."
- The nucleus is the part of a eukaryotic cell that contains the genetic material (DNA) organized into chromosomes, which include genes.

### Step 3: Evaluate the Truth of the Assertion
- The assertion is true because genes indeed play a crucial role in heredity and are responsible for the characteristics that offspring inherit from their parents.

### Step 4: Evaluate the Truth of the Reason
- The reason is also true; genes are located in the nucleus of eukaryotic cells.
- However, the reason does not provide a direct explanation for the assertion. While it is true that genes are in the nucleus, this fact alone does not explain how they are responsible for the transfer of traits.

### Step 5: Conclusion
- Both the assertion and the reason are true statements, but the reason does not correctly explain the assertion. Therefore, the correct conclusion is that the assertion is true, but the reason is not a valid explanation for the assertion.

### Final Answer
- The correct option is that the assertion is true, but the reason is false as it does not explain the assertion adequately.
