What Color Is It?

1 in 12 men and 1 in 200 women in the world suffer from color blindness- myself included. Color blindness is a sex-linked mutation that is found on the X chromosome. In humans, there are 2 sex-linked chromosomes. 2 X chromosomes develops as a female: XX- known as a redundancy. An X & Y chromosome develops as a male: XY- no redundancy. In order for a male to have color blindness, he needs to only have his X chromosome to have the gene coding for it- since he has one X and one Y. However, females need to have both of their chromosomes to have the mutation in order to have color blindness. One X becomes inactivated during embryonic development and usually, it would be the X with the mutation. If that other X doesn’t have it- no color blindness and if it does- color blind. That is why it is way more common in males than in females.
