Which of the following describes the characteristic shape of erythrocytes in Sickle Cell Anemia under deoxygenated conditions?

  1. Biconcave discs
  2. Microspherocytes
  3. Crescent-shaped
  4. Target cells
Show answer and explanation

Correct answer: Crescent-shaped

In Sickle Cell Anemia, a mutation in the beta-globin chain causes hemoglobin S to polymerize when oxygen levels are low. This polymerization deforms the erythrocyte into a rigid, sickle-like shape that can obstruct small blood vessels.
