I scored a 4 but I feel like I cheated considering that women can't be colourblind.
That is false its just significantly less likely to occur due to it being a sex linked trait, meaning the gene is on the X chromosome. The gene for colorblindness is recessive therefore if a man has the recessive gene on his X chromosome there's no chance he can have a dominant one to counter it, having only one X.
Women have two X's therefore they can have a recessive and a dominant and see normally. A woman can be colorblind but her father would HAVE to be colorblind and her mother would have to, at the very least, be a carrier.
