Q. Which of the following is an example of sex linked disease?
Solution:
Some genetic disorders are produced by changes in the genes lying in the sex chromosomes. These are called sex linked disorders. Colour blindness is produced by a recessive gene which lies on the X ; chromosomes. It occurs more common in men than in women. If a normal woman marries a colour blind man, ; they produce normal sons and carrier daughters. If a carier woman marries a normal man, half of the sons will be colour blind and half of the daughters will be carriers.
