Assertion : Restriction enzymes Hin and Hpa are produced from two different genera of bacteria.
Reason : Hin is produced from Haemophilus while Hpa is produced from Hematococcus.

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

### Step 1: Analyze the Assertion
The assertion states that "Restriction enzymes Hin and Hpa are produced from two different genera of bacteria."

- **Evaluation**: This statement is incorrect. Both Hin and Hpa are produced from the same genus, Haemophilus, but from different species. Therefore, the assertion is **false**.

### Step 2: Analyze the Reason
The reason states that "Hin is produced from Haemophilus while Hpa is produced from Hematococcus."

- **Evaluation**: This statement is also incorrect. Hin is produced from Haemophilus influenzae, and Hpa is produced from Haemophilus parainfluenzae. Both belong to the same genus, Haemophilus. Therefore, the reason is **false**.

### Step 3: Conclusion
Since both the assertion and the reason are false, we can conclude that the correct answer to the question is that both the assertion and reason are false.

### Final Answer
Both the assertion and reason are false.
