Question

Which is incorrect about thalassemia?

• A. This blood disease is transmitted from parents to the offspring when both the partners are unaffected carrier for the gene (or heterozygous)
• B. The defect is due to either mutation or deletion which ultimately results in reduced rate of synthesis of one of the globin chains that make up haemoglobin
• C. This causes the formation of abnormal haemoglobin molecule resulting into anaemia which is character istic of the disease
• D. Thalassemia differs from sickle cell anaemia in that the former is a qualitative problem of synthesising an incorrectly functioning globin while the latter is a quantitative problem of synthesising too few globin molecules

Answer 1

Answer: (D)

Sickle cell anaemia differs from thalassemia in that the former is a qualitative problem of synthesising an incorrectly functioning globin while the latter is a quantitative problem of synthesising too few globin molecules.
