Final Answer : D, Explanation :  Hemophilia is an X-linked recessive disorder that is caused by a mutation on the X chromosome. Since males have only one X chromosome, if they inherit the hemophilia gene, they will have the disorder. Females, on the other hand, have two X chromosomes, so even if they inherit the gene, they may still have a functional copy on their other X chromosome, and therefore not have the disorder. As a result, hemophilia is much more common in males than in females.
