Do man really colour blind?

So many times I witnessed woman teasing man about being colour blind. It got me interested to do a small research.

Aparently colour deficiency is much more common in (European) man (8%) then woman (0.4%). This is not an urban myth! This is because it is linked to the X chromosome. Man only have one X chromosome and would get a colour deficiency if it’s impaired. Woman with one good X chromosome will still recognise colours.

So ladies – next time a guy asks you if something matches, just give him a hand!

Whant a quick test? Within patters below are dots which form a number visible to those with a normal colour vision.
