Question

Quizplus · Accepted Answer

Duchenne's muscular dystrophy is inherited through a sex-linked recessive gene, which means it is carried on the X chromosome. Since males have only one X chromosome, they are more likely to be affected by diseases that are recessive on the X chromosome. Duchenne's muscular dystrophy is not uncommon, primarily affects boys, usually manifests in early childhood (not midadolescence to early adulthood), and is currently incurable.
