question 6 options:

The correct option is C. Color blindness is an example of sex-linked traits.

Explanation:

Sex-linked traits can be described as those traits for which genes are present on the sex chromosomes. In humans, as X chromosome is a lot bigger than the Y chromosome, hence majority of the sex-linked traits are present on the X chromosome.

Colour blindness is an X linked trait and is more common to men than to women. This is because the gene for colour blindness is present on the X chromosome. As men have only one X chromosome so they have more chances of this disease.
