Who is more likely to be colorblind?

men
women
sailors
everyone with the same probability
It is much less likely for a woman to be red-green colorblind than a man, since this common type of color blindness is caused by a recessive gene in the X chromosome. For a woman, both of her X chromosomes would have to be affected. A man only has one X chromosome, so he is more likely to be color-blind.
