Options

A. `1.5%`
B. `2.5%`
C. `5.9%`
D. 0.08

Answer

To determine the percentage of color blindness in the white male population, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Color Blindness**:
- Color blindness is a genetic disorder that affects an individual's ability to see colors or differentiate between them. It is primarily due to the presence of a defective gene on the X chromosome.

2. **Genetic Basis**:
- Since color blindness is an X-linked recessive trait, it predominantly affects males. Males have one X and one Y chromosome (XY), while females have two X chromosomes (XX). If a male inherits the affected X chromosome, he will express the trait because he does not have a second X chromosome to mask it.

3. **Prevalence in Population**:
- Research indicates that the prevalence of color blindness in the white male population is approximately 8%. This means that out of 100 white males, about 8 are expected to be color blind.

4. **Converting Percentage**:
- To express this prevalence as a percentage, we can state that 8 out of 100 is equal to 8%. This can also be expressed in decimal form as 0.08.

5. **Evaluating Options**:
- The question provides several options:
- 1.5%
- 2.5%
- 5.9%
- 0.008
- Since we know that the percentage of color blindness in the white male population is 8%, we can conclude that none of the provided options directly match this percentage.

6. **Conclusion**:
- The correct interpretation of the data shows that the percentage of color blindness in the white male population is approximately 8%, which is not listed among the options provided.
