What is the type of genetic inheritance of colour blindness? Is colour blindness more frequent in men or in women? What is the physiological explanation for colour blindness?

• Colour blindness is an X-linked recessive disorder. It is generally passed down from a carrier woman to male child.
• Colour blindness is more common in males than in females.
• The gene for colour blindness is present in X- chromosome. The disease is more common in males because of the presence of only one X-chromosome as compared to two X-chromosomes in females. Hence, colour blindness is more common in males than in females.
• Cone cells detect color and are concentrated near the center of your vision.
• The brain uses input from these cone cells to determine our color perception. Color blindness can happen when one or more of the color cone cells are absent, not working, or detect a different color than normal.
