Answer AND Explanation:

Let C be the allele for normal vision and is dominant to allele c for colour blindness.

XC Xc

Xc XCXc XcXc

Y XCY XcY

Genotype XCXc is a normal vision female but heterozygous that is carrier of that defective allele. The probability of the couple getting a colour blind child is 50%.
