Answer to Question 1

Ans:
B

Feedback:

Because of the association between congenital heart defects and Turner syndrome, an echocardiogram would most likely yield useful results. Turner syndrome is not associated with brain, skeletal, or liver involvement, and these tests would be less likely to provide useful insight.

Answer to Question 2

Ans:
B

Feedback:

When two chromosomes of the same number are inherited from one parent, the result can be the disorder of uniparental disomy. Answers A, C, and D all relate normal genetic processes.
