Why do some people inherit color blindness?
Human BiologyVision Genetics
Quick Answer
Most common red-green color blindness happens when genes for cone pigments on the X chromosome are altered. Because the genes are X-linked, it is much more common in males.
The Full Story
Color vision depends on cone cells in the retina that detect different wavelengths of light. The most common form of color blindness involves changes in the genes for red and green cone pigments, which sit on the X chromosome. Males have one X chromosome, so a single altered copy can cause the trait, while females usually need changes in both copies. This is why red-green color blindness affects roughly 8% of men of Northern European ancestry and far fewer women.
