natural selection and heredity Americans are affected with sickle cell anaemia which mostly affects black people.
Hi, Glutamate is replaced by valine in sickle cell anaemia
Malaria is common in topical ad subtropical zones. The malaria has selected the people with sickle cell anaemia. Although person with sickle cell anemia can have malaria, the carrier, or the person with sickle cell trait is resistant to malaria.
evolutionary advantage means that if you have to types of sickle cell anaemia and one is resistant to a drug the the other one is not then the one that is not resistant dies off and the sickle cell anaemia that is resistant becomes dominant and that is why sickle cell anaemia is still so widespread in Africa because the strain that is widespread in Africa is resistant is anti-biotics.
15000 people with sickle cell in the UK i think
Sorry there is no cure only treatment.
Most of them I would imagine.
20,000 people die with sickle cell each year
Sickle Cell Anaemia is a single gene defect (Hb gene).
antherosclerosis

Sickle Cell Anaemia is a genetic disorder that affects the red blood cells. The shape of the cells are changed from being round and flexible to sickle or crescent shaped. These abnormal cells can then clog the blood vessels, causing extreme pain and discomfort. These episodes are known as sickle cell crisis.
