Color blindness common in males.

Among humans males are more likely to be color blind than females because the genes responsible for the most common forms of color blindness are on the x chromosome. There is no treatment for color blindness when it is inherited. Colour blindness is more common in men than in women because the genes responsible for the color blindness are located on the x chromosome. The most common cause of color blindness is an inherited problem in the development of one or more of the three sets of the eyes cone cells which sense color.

You can inherit a mild moderate or severe degree of the disorder. It can affect about one in 20 men versus one in 200 women. It is much more common for men to inherit color blindness. The genes that can give you red green color blindness are passed down on the x chromosome.

Males have only one x chromosome whereas females have two x chromosomes. The most common color deficiency is red green with blue yellow deficiency being much less common. In males only one defective x chromosome is enough to cause colour blindness. In red green color blindness this means difficulty distinguishing between shades of red green and yellow.

Since it s passed down on the x chromosome red green color blindness is more common in men.
