What happens if a baby inherits two recessive genes for colour blindness?

If a baby inherits two recessive genes for color blindness, they will express the condition, as color blindness is typically an X-linked recessive trait. This means that if the baby is male, he will have color blindness if he inherits the recessive gene from his mother. If the baby is female, she would need to inherit the recessive gene from both parents to be color blind. In either case, the child will have difficulty distinguishing certain colors, commonly red and green.
