Quizplus · Accepted Answer

Hemophilia A is an X-linked recessive disorder, which means the genetic mutation causing the disorder is located on the X chromosome. Males only inherit one X chromosome from their mothers, so if the mother carries the genetic mutation, the son has a 50% chance of inheriting hemophilia A. Females inherit two X chromosomes, so they have a lower chance of inheriting hemophilia A as they would need to inherit the genetic mutation from both parents.
