Solution

The correct option is A Not show any symptoms of the disease
  • The chromosomes in males are X and Y. The sons will receive the Y chromosome from the father and X chromosome from the mother.
  • Since the man is suffering from X-linked dominant disease and the woman has normal complement of genes, the daughters (if any) will be diseased and none of the sons will be diseased.
    Thus the correct answer is option A.
