Question

Quizplus · Accepted Answer

Red-green color vision deficiency is an example of a sex-linked trait because the gene that controls color vision is located on the X chromosome. Males only have one X chromosome, so if they inherit a color vision deficiency gene, they will exhibit the trait. Females have two X chromosomes, so they are less likely to exhibit the trait unless they inherit the gene from both parents.
