Thalassemia

Vedclass · Answer

(D) Thalassemia is an autosomal recessive blood disorder caused by defects in the synthesis of globin chains of hemoglobin.It is classified into two types: $\alpha$-thalassemia and $\beta$-thalassemia.Unlike sickle-cell anemia,which is a qualitative defect (abnormal hemoglobin structure),thalassemia is a quantitative defect where there is a reduced synthesis of one of the globin chains ($ \alpha $ or $ \beta $),leading to the formation of abnormal hemoglobin molecules and anemia.
