Why don’t women get muscular dystrophy?

This is because The mutated gene that causes Duchenne is located on the X chromosome. Girls have two X chromosomes, which means that the body usually inactivates the chromosome that carries the mutation. Females will carry the mutation but show few symptoms of the disease.
