Quizplus · Accepted Answer

Color-deficient vision, also known as color blindness, is a sex-linked characteristic that is more common in males than females. This is because the gene for color vision deficiency is located on the X chromosome, and males only have one X chromosome while females have two. Therefore, if a male inherits the gene for color vision deficiency on his X chromosome, he will have the condition, while females need to inherit two copies of the gene (one from each parent) to be affected.
