What are the chances of a person with the disease passing the disease to their offspring?

Women have 2 X’s so it’s less likely for them to get the genetic disorder, but they can be carriers if one of their X is affected.  Males only have one X and they have a Y. If one of their Y’s is affected more than likely they have the disorder, if both their X and Y is affected they 100% have the Color Blindness.
For example, if a women with XX’ marries a guy with X’Y their child ,if a girl , would have 0% chance of having Color Blindness , but would be a carrier.  If they had a boy he would have a 25% chance of having the disorder, because his genotype would be X’Y , and  his X chromosome is affected he had the disease.
