alleryβ-Thalassemia is controlled by which gene?
AHBA1 and HBA2 on chromosome 16
BHBB on chromosome 11
CCFTR on chromosome 7
DF8 on the X chromosome
Answer & Solution
Correct answer: B. HBB on chromosome 11
**β-Thalassemia**: caused by mutation in the **HBB gene on chromosome 11**
→ reduced β-globin synthesis.
α-Thalassemia: HBA1, HBA2 on chromosome 16. (Haemophilia A: F8 on X.)
