Answer to Question 1

ANS: D
Barts (g4) hemoglobin is present at birth in all forms of a-thalassemia. Hb H inclusions, anemia, and microcytic red cells are not found in all forms.

Answer to Question 2

ANS: B
Hb H disease occurs when three genes are missing for a globin chain synthesis and an excess of b chains (b4), which is named Hb H, is present and easily detectable. A mild to moderate anemia is present. These individuals are primarily of Asian ethnicity.
