Duchenne muscular dystrophy (DMD) is inherited in an X-linked recessive pattern. Mitochondrial inherited disorders are inherited from the mother as the father's DNA is destroyed when the sperm and egg fuse. Examples of mitochondrial inherited disorders include Leigh syndrome and Pearson syndrome.

QuestionChoice
Duchenne muscular dystrophy (DMD) is inherited in an  X-linked recessive pattern. Males have only one copy of the X chromosome from their mother and one copy of the Y chromosome from their father. If their X chromosome has a DMD gene mutation, they will have Duchenne muscular dystrophy. Due to X-inactivation, it is rare that females (XX) suffer from DMD as this process means that all X chromosomes but one are silenced.
