Why is color blindness more common in males than in females?
Correct answer: D. Color blindness is a sex-linked genetic disorder
- A. Men do not take care of their eyes well enough
- B. Men spend more time in front of digital screens than women
- C. Men usually aren't able to distinguish between colors due to some circuitry in their right hemisphere of the brain
- D. Color blindness is a sex-linked genetic disorder
Explanation
Color blindness is more common in males because it is a sex-linked genetic disorder primarily associated with the X chromosome. Males have only one X chromosome, inherited from their mother. If that X chromosome carries the gene for color blindness, they will express the condition because they do not have a second X chromosome to potentially counteract it. Conversely, females have two X chromosomes, so a non-affected X chromosome can compensate for one that carries the gene for color blindness, reducing the likelihood of expressing the condition.The other options are incorrect because they attribute color blindness to non-genetic factors like eye care, screen time, or brain circuitry, none of which are relevant to the genetic inheritance of color blindness.
