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.
