None of the above

Explanation:
Detailed explanation-1: -Families with an X-linked recessive disorder often have affected males, but rarely affected females, in each generation. For X-linked dominant diseases, however, a mutation in one copy of an X-linked gene will result in disease for both males and females.
Detailed explanation-2: -Not to stir up a battle of the sexes, but the X chromosome (females have two of them, while males have one) is five times larger than the Y chromosome, and has 10 times the number of genes. That means it carries more traits-and diseases-than the Y chromosome.
