Answer to Question 1

ANS: A
Prader-Willi, an example of gene imprinting, is not associated with any autosomal sex-linked ab-normality.

Answer to Question 2

ANS: D
Duchenne muscular dystrophy is a relatively common X-linked recessive, not dominant, disorder. While it is sex linked, it is not X-limited or X-influenced.
