What causes muscular dystrophy to run in families?

A doctor has provided 1 answer

It's in the genes!: Many muscular dystrophies are caused by a defect in the genes. These defects are passed on to our children. Some are dominant meaning there is a 50/50 chance of passing it along, others are linked to gender or are recessive meaning you have to reproduce with someone with the same defect to have a child who is affected.
