In brief: X linked

The gene for the abnormal protein is located on the x chromosome.
Hence it is "x linked" . Mostly boys are affected.

In brief: X-linked inheritance

Duchenne muscular dystrophy is caused by a mutation of the dmd gene on the x chromosome.
A woman who is a carrier will pass the mutation (on average) to half of her sons and half of her daughters, but only the sons will develop muscular dystrophy - because they have only one x chromosome. Carrier females with one normal dmd gene are usually free of symptoms. Your genetic counselor can explain more.
