Answer to Question 1

ANS: D
In the United States, African American male subjects are the ethnic group that most commonly has G6PD A- deficiency. From 10 to 11 of these subjects carry this gene. The gene is X linked, so that female subjects are carriers and generally do not have clinical problems.

Answer to Question 2

ANS: C
After splenectomy, the anemia is usually corrected and reticulocyte counts return to high normal. However, the consequences of splenectomy, done for whatever reason, are the appearance of Howell-Jolly bodies, siderocytes, and target cells in red cells. Spherocytes will still be observable in hereditary spherocytosis.
