Quizplus · Accepted Answer

X-linked traits are located on the X chromosome, which is only present in males as a single copy. Therefore, if a male inherits an X-linked mutation, he will express the trait, whereas a female would need to inherit two copies of the mutation (one from each parent) to express the trait. This means that X-linked traits tend to affect males more than females.
