Assertion: Dominance is not an autonomous feature of a gene or the product that is has information for.
Reason : Dominance depends much on the gene product and the production of a particular phenotype from this product.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1)
B. If both Assertion & Reason are true and the reason is not the correct explanation of the assertion , then mark (2)
C. If Assertion is true statement but Reason is false, then mark (3)
D. If both Assertion and Reason are false statements, then mark (4)

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that "dominance is not an autonomous feature of a gene or the product that it has information for." This means that dominance does not solely depend on the gene itself or its product (like a protein).

2. **Analyzing the Reason**: The reason provided is that "dominance depends much on the gene product and the production of a particular phenotype from this product." This indicates that the expression of dominance is influenced by the protein produced by the gene and how this protein contributes to the observable traits (phenotype).

3. **Evaluating the Truth of the Statements**:
- The assertion is true because dominance is context-dependent and can vary based on the interaction between alleles, especially in heterozygous conditions.
- The reason is also true because the gene product (usually a protein) is essential for the manifestation of traits, and the dominance of one allele over another often results from the functional protein it produces.

4. **Connecting Assertion and Reason**: The reason explains the assertion well. Since dominance is influenced by the gene product and its role in phenotype expression, it supports the idea that dominance is not an autonomous feature.

5. **Conclusion**: Both the assertion and reason are true, and the reason correctly explains the assertion. Therefore, the answer is that both statements are true, and the reason is the correct explanation of the assertion.

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