Answer:
0 percent chance.
Step-by-step explanation:
If it is a male then the mom has to be a carrier or have the trait because the dad will pass on a Y, and the trait for colorblindness is linked to the X. If it is a female, she needs 2 of those traits (one from each parent), and since the mom cannot give one, there is not a chance of the kids having colorblindness.
