Answer to Question 1

ANS: C
In adults, the approximate concentration of hemoglobin A (Hb A) (a2b2) is 96; of Hb A2 (a2d2), 2; and of hemoglobin F (Hb F) (a2g2), 2.

Answer to Question 2

ANS: B
Hb E is a variant found in Southeast Asian populations. It migrates with Hb C on cellulose acetate alkaline electrophoresis. Because Hb A is also present, this patient probably has Hb E trait (is not homozygous for Hb E). The MCV is low and target cells are present in this trait.
