Answer:
- Mother´s genotype: X⁻ X⁻
- Father´s genotype: X⁺ Y
- Son´s genotype: X⁻ Y
- Daughter´s genotype: X⁺X⁻
- The probability of having a color-blind son, X⁺Y, is 2/2 = 100%
- The probability of having a color-blind daughter, X⁻X⁻, is 0%
- The probability of having a carrier daughter, X⁺X⁻, is 2/2 = 100%
