TEDIOUS FACT: women can carry the genes for hereditary colour-blindness but will not display any symptoms.

In most cases the female will be only a carrier, but it is certainly possible for a female to display the symptoms of genetic colour-blindness, if she inherits a full set of wonky genes (scientific term there).

I was about to say this
Gene is carried on the X chromosone so if a girl has 2 dodgy ones she'll have it. Just less likely to have it than a boy.

not true...
50 out of 10,000 women are colour blind, 800 out of 10,000 men are.

Bad Gene
is carried on the X chromosone, just like haemophilia. So if a boy has a dodgy X, he only has one as the Y can't take over, so he will have it. Girls, however, have 2 Xs, so if they have one dodgy X they won't have it as the good one will take over. If a girl has two dodgy Xs she'll have it. It's twice as likely she'll only have 1 dodgy one than 2, if *both* her parents are carriers. For a boy to get it, only one parent needs to be a carrier. Hence much more likely for a boy to have it. The reason females are even less likely to have haemophilia despite it being carried in the same way is that she needs both parents to carry a specific gene each which is very rare.
