The daughters of this couple will have normal eye sight but would be carrier. If one of the carrier daughter marries with normal eyed man,

  1. Normal woman
  2. Colourblind man
  3. Carrier daughter
  4. Normal eyed man

Correct answer: Carrier daughter

Solution

Color blindness is X-linked recessive. A carrier daughter has one normal X and one colorblind X, so when she marries a normal-eyed man, some daughters can inherit the affected X from her and the normal X from him, making them carriers.
