Question

Men are more likely to have color vision deficiency than are women.​

Quizplus · Accepted Answer

Color vision deficiency is an inherited condition that occurs more frequently in men than in women. This is because the genes responsible for the most common types of color vision deficiency are located on the X chromosome, and men have only one X chromosome while women have two. Therefore, if a man inherits a faulty color vision gene on his X chromosome, he will have color vision deficiency, whereas a woman may have one faulty gene but still have normal color vision if the other X chromosome carries the normal gene.
