The correct answer is TrueColorblindness is more common in males because the genes responsible for the most common types of colorblindness are found on the X chromosome. Males only have one X chromosome, so if that chromosome carries the gene for colorblindness, they will show the condition. Females, on the other hand, have two X chromosomes, so the normal gene on one X can often compensate for the defective gene on the other. This makes colorblindness less common in females.
