Science fact: Men are more likely to be colorblind than women

Science fact: Men are more likely to be colorblind than women. The genes responsible for the most common type of colorblindness are found on the X chromosome, the National Eye Institute explains. Even if women have the genes on one of their two X chromosomes, a properly functioning gene on the other one makes up for that loss. If men inherit the gene on their only X chromosome, they’ll become colorblind.
