As muscular dystrophy is a genetic disease, genetics play a big role in its epidemiology. The dystrophin gene is carried in the X-chromosome. Females have 2 X-chromosomes whereas males have one X-chromosome and one Y-chromosome.

Boys, on the other hand, are openly susceptible as they have only one gene-carrying X-chromosome.
