Sickle Cell Anaemia is called a recessive condition because you must have two copies of the sickle haemoglobin gene to have the disorder. Sickle haemoglobin is often shortened to S or HbS. If you have only one copy of the sickle haemoglobin along with one copy of the more usual haemoglobin (A or HbA) you are said to have Sickle Cell Trait.

Sickle cell disease is a genetic blood disease which affects the whole life of an affected patient. It is more common in the tribal population of India but occurs in non-tribals too.
