What is the chance of passing this disease to your offspring?

This disease, like I mentioned before, is not as prevalent in females as it is in males. Here is why.

If a father is colorblind, but not the mother (she is not even a carrier), then no male children will be colorblind and all female offspring will be carriers. If the father is colorblind but the mother is a carrier, then there is a 25% chance that a female child will be colorblind, a 25% chance that a female will be a carrier, a 25% chance that a male child will be colorblind, and a 25% chance that a male will not be colorblind. If a fully colorblind male marries a fully colorblind female, then all children will be colorblind. Lastly, if a mother is a carrier but the father is not colorblind, there is a 50% chance that the female children will be carriers, and a 50% chance that male children will be affected.
