Answer 1

Answer:

I hope the answer is albinism

Answer 2

Colour blindness is genetically similar to haemophilia.

* Both are X-linked recessive disorder.

* The females are the carriers of such disorders as they have two X chromosomes.

* Since, it is a recessive disorder, a person is affected only if both the X chromosomes( in females) carries the defect.

* In case of males, there is only one X chromosome so they are either affected or unaffected. They can never be the carriers.
