Thalassemia and sickle cell anaemia are caused due to a problem in globin molecule synthesis. Select the correct statement.

In α-Thalassemia, production of α globin chain is affected while in β-Thalassemia, production of β globin chain is affected. 

Alpha globin chain is controlled by two linked genes present on the chromosome 16, while beta globin chain is controlled by a single gene present on the chromosome 11.
