Answer

To determine which statement about color blindness is correct, we can analyze the information provided in the video transcript step by step.

### Step-by-Step Solution:

1. **Understanding Color Blindness**:
- Color blindness is primarily an X-linked recessive condition. This means that the gene responsible for color blindness is located on the X chromosome, and the condition is more common in males than females due to the presence of only one X chromosome in males.

2. **Types of Color Blindness**:
- There are two main types of color blindness mentioned:
- **Deuteranomaly**: This is a type of green color blindness.
- **Protanomaly**: This is a type of red color blindness.

3. **Prevalence of Color Blindness**:
- According to the transcript, the prevalence rates are:
- **Deuteranomaly (Green Color Blindness)**: 6% of males and 0.4% of females.
- **Protanomaly (Red Color Blindness)**: 2% of males and 0.01% of females.

4. **Correcting the Statements**:
- The transcript initially states that 6% of men are red colorblind and 2% are green colorblind, which is incorrect. The correct statement is that 2% of men are red colorblind (protanomaly) and 6% of men are green colorblind (deuteranomaly).

5. **Conclusion**:
- The correct statement regarding color blindness is that 6% of men are green colorblind (deuteranomaly) and 2% are red colorblind (protanomaly).

### Final Answer:
The correct statement about color blindness is:
- 6% of men are green colorblind (deuteranomaly) and 2% are red colorblind (protanomaly).
