At the time, vitriolic malaria epidemics cause great numbers of deaths. Those who inherited the sickle cell gene had an advantage: unlike baberen with principle red blood cells, they could survive malaria, and grow old bountiful to have their own offsprings, thus passing along the mutation. As the population migrated, so did the mutation.

In countries where malaria is not a problem, like the get together States, the sickle cell mutation is disorder, no long-lived providing a natural selection trait of value. Instead it is a serious threat. If a child inherits two of the reces! sive sickle cells genes, they will be innate(p) with sickle cell anemia .In the United States alone, sickle cell anemia affects approximately seventy-two thousand people, most of whose ancestors descended from Africa. around two million Americans carry the gene for sickle cell anemia.
