Quizplus · Accepted Answer

Duchenne's muscular dystrophy is caused by a mutation in the dystrophin gene located on the X chromosome. Since it is X-linked, it mainly affects males. Females can inherit the disease if they receive the mutated X chromosome from both parents, but this is rare. Therefore, option A is the best choice.
