Sickle cell anemia and leukemia highlight the genetic and environmental factors influencing blood disorders, emphasizing their significance in understanding hereditary conditions and familial health risks. Sickle cell anemia is a genetic disorder that can be passed through families, illustrating the importance of genetic counseling and testing for at-risk individuals. Leukemia, while not solely hereditary, can have familial patterns, underscoring the need for awareness of family medical histories. Together, these conditions stress the importance of early detection, treatment options, and support for affected families.
natural selection and heredity Americans are affected with sickle cell anaemia which mostly affects black people.
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.
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.

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.
Sickle Cell Anaemia is a single gene defect (Hb gene).
