What's the probability of a couple having a child with muscular dystrophy, if mom is the carrier?

In brief: Depends

This depends entirely on the type of muscular dystrophy and the type of inheritance pattern.
Some disorders are dominant, meaning there is a 50/50 chance of passing it on, some are recessive meaning you need to reproduce with another carrier to pass it on, and some are x linked. One form, duchenne muscular dystrophy is always x linked and carrier moms have a 50% chance of passing it to their sons.

In brief: For Duchenne...

Unfortunately, 50% of boys will have dmd, 50% of girls will be carriers.
