Answer 1

Colour blindness:

2. There are three types of colour blindness, they are: Red-green colour blindness, blue-yellow colour blindness and complete colour blindness or monochromacy.
3. Males are more prone to this disease as they inherit only one copy of the X chromosome.

5. In order for a female to be colour blind, her mother has to be a carrier of the defective gene and father has to be colour blind.
