Question

Quizplus · Accepted Answer

Color blindness is more common in males due to the fact that the genes responsible for the most common, inherited color vision deficiencies are on the X chromosome. Since males have only one X chromosome, a single altered gene can cause color blindness. Females have two X chromosomes, so a mutation would have to occur in both copies of the gene to cause the disorder, making it less common in females.
