Quizplus · Accepted Answer

Most sex-linked disorders are caused by recessive genes located on the X chromosome. This is because males have only one X chromosome, making them more susceptible to inheriting a disorder if it is present on that chromosome. Females, on the other hand, have two X chromosomes, which allows for some compensation if a disorder is present on one of them.
