Assertion (A) The duplicate genes are also called pseudoalleles.
Reason ( R) Duplicate genes although present on different locus but have the ability to produce same or almost same trait of a character.

Options

A. Both Assertion and Reason are true and the Reason is the correct explanation of the Assertion
B. Both Assertion and Reason are true, but Reason is not the correct explanation of the Assertion
C. Assertion is true, but Reason is false
D. The Assertion and Reason both are false

Answer

### Step-by-Step Text Solution

1. **Understanding the Assertion (A)**: The assertion states that "the duplicate genes are also called pseudoalleles." To evaluate this, we need to understand the definitions of both terms. Duplicate genes refer to genes that can produce similar traits but are located at different loci on the chromosomes. Pseudoalleles, on the other hand, are typically alleles that are closely linked and can exhibit similar effects due to their proximity.

**Hint**: Look up the definitions of duplicate genes and pseudoalleles to clarify their differences.

2. **Evaluating the Reason (R)**: The reason states that "duplicate genes, although present on different loci, have the ability to produce the same or almost the same trait of a character." This statement is accurate. Duplicate genes can indeed produce similar phenotypic effects, even though they are located on different chromosomes or loci.

**Hint**: Consider examples of traits influenced by duplicate genes to see how they can produce similar outcomes.

3. **Conclusion on Assertion and Reason**: Since the assertion is incorrect (duplicate genes are not the same as pseudoalleles), and the reason is correct (duplicate genes can produce similar traits), we conclude that the assertion and reason are not aligned. Therefore, the correct answer is that the assertion is false, while the reason is true.

**Hint**: Remember to differentiate between the correctness of the assertion and the reason when evaluating such statements.

4. **Final Answer**: The assertion is incorrect, and the reason is correct. Thus, the answer is option number 4: both the assertion and reason are false.

**Hint**: When answering assertion-reason questions, always check the relationship between the two statements to determine their truthfulness.
