Why is it so rare for women to have color blindness?



  1. 0 Votes

    The most common type of color-blindness is a recessive sex-linked trait, which means that it is carried on the X chromosome. Women have two X chromosomes, while men have only one X and one Y. This means that a woman must inherit two genes for color-blindness (if the gene is on one chromosome, the normal gene will be dominant over it) while a man only needs to inherit one. This also means that a woman can be a “carrier” for color blindness and pass it on to her male children, though she can see color.
