Question

Name any one X - linked disease found in humans.

Answer 1

Red, Green Colour Blindness

1. X - linked disease is a recessive sex - linked trait.
2. X - linked disease most affects the male population because males have only one copy of the X - chromosome.
3. In red, green colour blindness, a human being cannot distinguish between red and green colours.
4. A female human being suffering from the disease has the gene complement X^CX^C, while a male human being suffering from the disease has the gene complement X^CY.
5. A female who is not suffering from the disease but is a carrier of the disease has the gene complement X^CX or XX^C.
