Quizplus · Accepted Answer

Color vision deficiency is a sex-linked trait because the gene for color vision is located on the X chromosome. Since males only have one X chromosome, they are more likely to inherit color vision deficiency if the X chromosome they receive from their mother carries the gene for it. Females have two X chromosomes, so even if one X chromosome carries the gene for color vision deficiency, the other X chromosome can compensate and still allow them to see colors normally. Eye color, temperament, and intelligence are not sex-linked traits.
