What are the differences between duchennes muscular dystrophy and myotonic muscular dystrophy?

Both are inherited: neuromuscular disorders. DMD is caused by mutatation(s) on Chr. X. Onset of rapidly progressive muscle atrophy starts early in boys. Female carriers can have heart muscle disease. MD 1 is caused by mutant genes on Chr. 19; MD 2 by mutant genes on Chr. 3, Each child of a parent affected by either has a 50% chance of inheriting it, often with earlier & more severe symptoms than the parent's.
