Duchenne and Becker muscular dystrophies develop as a result of mutations in the DMD gene located on the sex X chromosome.
Since a man only has one X chromosome, if he has this mutation, he will develop the aforementioned diseases.
Females are more likely to carry mutations in the DMD gene (one of the X chromosomes contains a mutated DMD gene), as having a mutated gene on both X chromosomes is rare.
