Sickle Cell Anemia

Should we be concerned?

History

Sickle cell anemia is an inherited form of an anemia is the condition in which there aren't enough healthy red blood cells to carry adequate oxygen throughout your body and the red blood cells become rigid and sticky and are shaped like sickles or crescent moons these irregularly shaped cells can get stuck in small blood vessels which can slow or block blood flow and oxygen parts of the body

How did sickle cell anemia became an example of natural selection ?

The people with the sickle cell gene they are protected against malaria but the populations where the malaria is Prevelant have a higher rate of sickle cell genes and in malaria endemic regions of Africa the Homogenous sickle cell and heterogenous trait would be selected for as it increases the probablity that the human will reach the age of fertility and be able to reproduce and heterogenous sickle cell trait is nearly asymptomatic and natural selection has a little effect on it places where Malaria does not exist and the homogenous sickle cell would be selected against in the regions without malaria due to its fatal side effects

The First Necessities for natural selection for all populations have genetic variation of sickle cell anemia

The Fourth necessities for natural selection to support sickle cell anemia

The support of sickle cell anemia is that to make you feel healthy and to have healthy blood vessels and normal blood cells

The Future of Sickle Cell Anemia

Treatments to save people's lives and to make children live life because they dont want to die at a young age
