The gene HBB for β-thalassemia is present on which chromosome?
- 5
- 22
- 11
- 9
The Correct Option is C
Approach Solution - 1
The HBB gene, which codes for the beta-globin part of hemoglobin, is located on chromosome 11. Mutations in the HBB gene can lead to β-thalassemia, a blood disorder that affects hemoglobin production.
Thus, the correct answer is (3) 11.
Approach Solution -2
The HBB gene is located on chromosome 11. This gene encodes the β-globin chain of hemoglobin, and mutations in this gene are linked to β-thalassemia, a blood disorder. Remembering gene-chromosome associations like HBB on chromosome 11 is helpful for genetics-based questions.
