Colour blindness

Wow, I was just enlightened by the fact that one out of every 10 guys are colour blind!...

ok fine, maybe you all knew that already. haha but i only just knew!
so they get to ask examiners the colour changes during chem and bio prac! wow:)
oh yea, and this is because guys have a higher chance of getting the disease due to only needing 1 copy of the colour blind gene to be infected whereas females need two of it.
