Color Blindness

Color blindness is a genetic inability to distinguish between certain colors, most commonly between red and green. This defect, which is characteristically male, is inherited through the mother. That is, a woman whose father was color blind can pass the trait to her son without herself suffering the defect. About 8 million people in the United States have the red/ green form of color blindness which can neither be cured nor corrected. Many of them are scarcely aware of their deficiency. Parents who suspect that their child may have this minor disability can arrange for simple testing.
