This forms long, rod- give care structures which cause the loss simple eye booths to change and assume a reap hook shape. With the deformity, the cubicles can non clinch through the crosscurrent vessels, depriving organs and tissues of oxygen Normal blood mobile phones represent for about one hundred twenty daylight in the blood, while the defective reaping hookd cells live only ten dollar bill to twenty. Because of their runty lifespan, the blood is constantly deficient in red blood cells, a condition kn suffer as anemia. Sickle cell anemia is a genetic disorder that resulted from a mutation which occurred 1000s of geezerhoo d ago in Africa, the Mediterranean basin, the pump East, and India. At the time, vitriolic malaria epidemics cause great numbers of deaths. Those who inherited the sickle cell gene had an advantage: unlike baberen with public red blood cells, they could survive malaria, and grow old generous 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 linked States, the sickle cell mutation is disorder, no weeklong providing a natural selection trait of value. Instead it is a serious threat. If a child inh erits two of the recessive sickle cells gene! s, 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.
