Color blindness may make some educational activities more difficult. It can impair such tasks as selecting ripe fruit choosing clothing and reading traffic lights. Color blindness is a trait linked to the x chromosome.
Red green color blindness is a sex linked genetic mutation on the opn1lw or opn1mw gene that is passed on the x chromosome. Men have 1 y and 1 x chromosome whereas women have 2 x chromosomes. With only one unaffected x chromosome color blindness can be prevented.
Though color blindness is a rare occurrence in women it can still occur. The absence of one or more of these cones leads to colour blindness. With this condition the gene is passed from the parent to the child on the x chromosome.
