Answer to Question 1

ANS: B
Trisomy 21 is associated with a number of notable physical characteristics, including wide-set eyes, flat bridge of the nose, protruding tongue, short neck, small chin, poor muscle tone, and space between the great and second toes. An infant with trisomy 21 tend to be short in stature and developmentally delayed, but two characteristics will become more noticeable as the child gets older. Cleft palate and polydactyly are more common with trisomy 13.

Answer to Question 2

ANS: C
Type AB blood indicates that the parental contribution was types A and B, which are considered dominant genes.
