Question

Quizplus · Accepted Answer

Hemophilia A is caused by a mutation in the F8 gene on the X chromosome. Since males have only one X chromosome, if they inherit the mutated gene, they will develop hemophilia A. This means it is a recessive disorder that primarily affects males. Females, on the other hand, have two X chromosomes, and if one of them carries the mutated gene, they can still produce enough clotting factor to avoid severe symptoms, so it is not primarily seen in females.
