FACT

Colorblindness is a sex-linked trait - the X chromosome is responsible. Since it only takes one 'good' X chromosome to prevent color blindness, women can be carriers without being colorblind themselves. However, if a man has a defective X chromosome, he will be colorblind, since he doesn't have a second X chromosome to back it up and take over.

OTHER

Color blindness in women is very rare. Only about 0.5% of all women have some kind of color vision deficiency and often this isnt even recognized. Most people think color blindness is only mans business but that is wrong.
