Sickle cell anemia is a genetically inherited autosomal recessive trait in which results in a condition that there are not enough healthy red blood cells to carry oxygen throughout the body due to the production of red blood cells that are sickle-shaped. The frequency of the sickle cell condition is as high as 10% in Central Africa compared to 0.5% in the United States.
a. Calculate the frequency of the normal and carries of the sickle cell condition.
b. Malaria is a disease caused by a parasite that infects healthy red blood cells and can lead to death. However, the parasite is not able to infect sickle cell red blood cells. Scientists claim that the higher frequency of sickle cell carriers is due to the presence of malaria. Provide reasoning to support the claim.
