Quizplus · Accepted Answer

Hemophilia is an X-linked disorder, which means that the mutation causing the disorder is located on the X chromosome. Males have one X and one Y chromosome, while females have two X chromosomes. Therefore, if a male with hemophilia has children, he will pass on the mutated X chromosome to all of his daughters, making them carriers of the disorder. Sons, on the other hand, will receive their X chromosome from their mother and their Y chromosome from their father, meaning they have a 50/50 chance of inheriting the disorder.
