Colourblindness is genetic, so you get it from your parents, its on the X chromosome, the reason that more guys than girls are colourblind is that the girls have 2 X chromosomes, so if one is defective (has the colourblindness gene) they can use the other chromosome that is in perfect working order. In males, we only have 1 X chromosome, so if our ones got the colourblindness gene we dont have an alternative chromosome to use, which is why we are more likely to suffer from it.

It's from DNA, specifically the X chromosome. What color-blindness is someone missing a cone photopigment type. Each eye has rods and cones. Cones let you see color. Everyone has red, green and blue cones. All colors, even white, can be made from a specific mixture of these 3 colors. The brain interprets the signals from the cones and determines the color. When someone is missing a photopigment, they are unable to see that color. So people missing the green photopigment confuse red and green but can still see in color. When someone is missing 2 photopigments, they only see black and white.

It is defianetly DNA, it is an inherited recessive gene that is usualy passed down by the mother and is usually common mainly in men.

Its often genetic and its a defect in the eyes themselves. The colorblind person does not have the correct color receptors in the eye.

It is passed genetically, and is in the DNA.
