    Colourblindness is a X-linked recessive disorder. One copy of the affected gene in males in each cell is sufficient to cause the disorder (XcY). Females with two copies of the affected gene show the disorder (XcXc). Females heterozygous (XcX) for this trait are normal but serve as a carrier of the disease. According to the question, the female is colourblind (XcXc) and father is normal (XY). The affected mother will inherit the disease to 100% sons  (XcY) while the 100% daughter will be normal but will serve as carrier. Correct answer is option B. Parent generation: (XcXc)   x  XY
