D) all colourblind
Correct Answer: D
Solution :
Colourblindness is a disease in which a person is unable to differentiate between red and green colour. The gene for this disease is located on the X-chromosome. So, if a colourblind woman marries a normal man, it will produce all the sons colourblind \[({{X}^{C}}Y)\]. In case of a carrier woman the probability of a colourblind and a normal son is 50 : 50.You need to login to perform this action.
