Why Is Color Blindness More Common In Males

The most common form of color blindness is called red green color blindness which is a loss of or limited function of the red cone.

Why is color blindness more common in males.

Colorblindness is more common in males than in females because it is considered to be a sex linked trait. 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. In this case the gene for this trait is located along the x chromosome and males tend to. The information for the red cone is in the x chromosome.

The genes that can give you red green color blindness are passed down on the x chromosome. However color blindness can be acquired and caused by many diseases that affect the retina or the optic nerve. The most common form of color blindness is inherited. Have certain eye diseases like glaucoma or age related macular degeneration amd have certain health problems like diabetes alzheimer s disease or multiple sclerosis ms.

Women are more likely to carry the defective chromosome responsible for passing on color blindness but men are more likely to inherit the condition. Men have a much higher risk than women for color blindness. Color blindness is more common in men. It s also way more common in men than in women.

While colour blindness could be a result of disease trauma or drug toxicity it s most commonly a result of genetics. Males have only one x chromosome whereas females have two x chromosomes. Males have 1 x chromosome and 1 y chromosome and females have 2 x chromosomes. As we mentioned it was all in the genetics.

The x chromosome mutation. Women can be carriers of hereditary forms of color deficiency that is passed through a defect in the x chromosome. White men are disproportionately affected. This is the form that is way more common in men.

The mutation for colour blindness is carried on the x chromosome. People with an x chromosome and a y chromosome only need their one x to be defective to catch it. People with two x chromosomes need both to be defective. 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.

Have a family history of color blindness. The most commons forms of colorblindness are genetic conditions passed along the x chromosome. So why is it that this visual deficiency occurs among males so much more frequently. Since it s passed down on the x chromosome red green color blindness is more common in men.
