Solution
The correct option is C Colour blindness
Colour blindness is the inability or decreased ability to see colour, or percieve colour differences, under normal lighting conditions. The genes that produce photopigments are carried on the X chromosome; if some of these genes are missing or damaged, colour blindness will be expressed in males with a higher probability than in females because males only have one X chromosome.
