Answer to Question 1

ANS: B
The most common cause of insufficient erythropoiesis is iron deficiency, not genetic factors, not a hemoglobin abnormality, not an erythrocyte structural abnormality.

Answer to Question 2

ANS: A
Hb S is formed by a genetic mutation in which one amino acid (valine) replaces glutamic acid. Valine has replaced glutamic acid. Hb S is formed by a genetic mutation in the amino acid (va-line), not proline, or histidine.
