The chance that a daughter will be colorblind depends on whether the father is colorblind or not. If the father is colorblind, then the daughter will be a carrier of the gene for colorblindness, but will not be colorblind herself. If the mother is a carrier of the gene and the father is not colorblind, then each daughter has a 50% chance of being a carrier and each son has a 50% chance of being colorblind. However, if the father is colorblind and the mother is not, then each daughter has a 50% chance of being a carrier and each son has a 50% chance of being colorblind. Therefore, the chance that a daughter will be colorblind depends on the genetic makeup of both parents.
