Color vision is on the X chromosome, making color blindness much more common in males than in females Men are much more likely to be colorblind than women, because the genes responsible for the most common, inherited color blindness is on the X chromosome. Males only have one X chromosome, while females have two X chromosomes.
Color (color) blindness (color vision deficiency, or CVD) affects approximately 1 in 12 men (8%) and 1 in 200 women in the world. In Britain, this means that there are approximately 3 million color blind people (about 4.5% of the entire population), most of whom are male. Worldwide, there are approximately 300 million people with color blindness, almost the same number of people as the entire population of the USA.
Most color-blind people can see things as clearly as other people but they are unable to fully ‘see’ red, green, or blue light. There are different types of color blindness and there are extremely rare cases where people are unable to see any color at all. The most common form of color blindness is known as ‘Red/Green color.
