QuestionChoice
Duchenne muscular dystrophy is inherited in an X-linked recessive pattern which means that males are more likely to be affected by the disease than females. This is because females can be carriers if they inherit one faulty and one normal X chromosome. Males cannot be carriers: they can either have the disease or not have the disease due to only inheriting one X chromosome.
