(1) 25 %
(2) 0 %
(3) 50 %
(4) 75 %
 

Dear student.

The correct answer is (3) 50 %.

Here, Man will be normal, as colour blind passes from mother to son and father to daughter. Women will be carrier, as her father was normal.
 


Out of two male children, 1 is normal and 1 is having colour blindness.


Regards.
