Why is color blindness more common in males than in females?
Correct answer: C. Color blindness is a sex-linked genetic disease
- A. Men do not take care of their eyes well enough
- B. Men spend more time in front of digital screens than women
- C. Color blindness is a sex-linked genetic disease
- D. Men usually aren't able to distinguish between colors due to some circuitry in their right hemisphere of the brain
Explanation
Since it's passed down on the X chromosome, red-green color blindness is more common in men. This is because: Males have only 1 X chromosome, from their mother. If that X chromosome has the gene for red-green color blindness (instead of a normal X chromosome), they will have red-green color blindness.

About Scientific Reasoning
Scientific reasoning evaluates hypotheses through observations, variables, controls, measurements and experimental results. Questions involve identifying independent and dependent variables, recognising a fair test, interpreting tables or graphs, distinguishing evidence from opinion, and deciding whether data supports, rejects or leaves a hypothesis unresolved.
