D. Assertion is false but Reason is true

Answer

To solve the assertion and reason question regarding color blindness, we can follow these steps:

### Step 1: Analyze the Assertion
The assertion states: "There are more color blind men than women throughout the world."

- This statement is **true**. Color blindness is indeed more prevalent in men than in women due to genetic factors.

### Step 2: Analyze the Reason
The reason states: "Color blindness is a sex-linked disease resulting from a recessive gene on the Y chromosome."

- This statement is **false**. Color blindness is actually an X-linked recessive disorder, not Y-linked. The gene responsible for color blindness is located on the X chromosome.

### Step 3: Determine the Relationship Between Assertion and Reason
- Since the assertion is true and the reason is false, the reason does not correctly explain the assertion.

### Conclusion
- The assertion is true, but the reason is false. Therefore, the correct answer is that the assertion is true, and the reason is false.

### Final Answer
- Assertion: True
- Reason: False
