Question

Sickle-cell anaemia is a genetic disorder.

• A. True
• B. False

Answer 1

The correct option is A True

• Sickle-cell anaemia is a genetic disorder since, it arises due to a mutation in the gene that codes for haemoglobin. This mutation causes the replacement of glutamic acid by valine at the sixth position of the haemoglobin chain.
• If both father and mother are suffering from sickle-cell anaemia or are carriers, then their offspring will suffer from this disease.
