Answer to Question 1
C
Duchenne muscular dystrophy is a recessive sex-linked disease carried on the X chromosome so only males are affected with the disease. Because Duchenne muscular dystrophy is a recessive X-linked disorder, females can only be carriers and do not have the disease. The disease is an X-linked recessive disorder and would not be found on the Y chromosome. The disease is a recessive X-linked disease and is always carried by the mother.
Answer to Question 2
B
Intermittent joint pain lasting longer than 6 weeks is indicative of juvenile arthritis. Frequent fractures are indicative of osteogenesis imperfecta. Increased joint mobility is indicative of osteogenesis imperfecta. Lurching to the affected side causing an abnormal gait and limited abduction are associated with the developmental dysplasia of the hip (DDH).
