Answer to Question 1

D
Feedback:
Duchenne muscular dystrophy follows an X-linked recessive inheritance pattern. Limb-girdle muscular dystrophy is believed to be autosomal or X-linked inherited. Myotonic and distal muscular dystrophy follow an autosomal dominant inheritance pattern.

Answer to Question 2

B, D, E
Feedback:
Any type of spinal muscular atrophy is a genetic motor neuron disease due to autosomal recessive inheritance. Type 2 SMA usually occurs between 6 and 18 months of age, with weakness that is most severe in the shoulders, hips, thighs, and upper back. It is slower in progression than type 1 . Survival into adulthood is common if respiratory status is maintained appropriately. Type 1 SMA occurs before birth to 6 months of age and the child usually has difficulty swallowing, sucking, and breathing.
