Was Your Ancestor Color Blind?


What do most of us see when we look at this image? An orange 6 against a green background, right? Not so for colorblind folks. 

According to Ask Marilyn in the Sunday Parade magazine up to 8% of men and only 0.5% of women, depending on their ancestry, have some degree of color deficiency, usually caused by defective or absent photo-pigments in the retina. The most common types are inherited, so if a family member is known to have a color vision problem, it's important to test all the children who may be unaware of their disorder. 

** Did you have an ancestor who was colorblind? Likely they never knew............ they did not have to match a necktie to a shirt. 

** Both Robert Redford and Prince William suffer from colorblindness.
