color+blindness

2008 7% of the population of men have Red Green Color Blindness. Where as only .4% of women do. That is because it is carried on the X chromosome. So because females have two they have a less chance of getting it. Some scientists have found that the red and green cones in the eyes of those with the color blindness work improperly or not at all. They think this that they must have been altered some time to cause this. They tested someone who was not color blind and found they had an extra green receptor gene. He realized that the red and green receptor genes are really similar and the way the lie it is very easy to make a mistake in the development process. So some people might have an extra green receptor but it doesn’t do anything but than you have two green to one red. The person who inherits this will be color blind. Most colorblindness involves the red and green receptors. It is very rare for it to end up on the blue side of the spectrum.
