Even though this mutation is helpful in avoiding malaria‚ this mutation can also lead to sickle cell anemia. Sickle cell specialist Dr. Ronald Nagel stresses the genetic variety necessary for the existence of a species. A gene known as HbS was the center of a medical detective story that began in the middle 1940s in Africa. Doctors noticed that patients who had sickle cell anemia‚ a serious inherited blood disease‚ were more likely to survive malaria. What was confusing was why sickle cell anemia

Sufian argues

HbS is 3:1; in a typical population‚ the Homozygous Dominant Gene would become the standard‚ but because carrying the Heterozygous version of the allele has an advantage to fighting Malaria it will become the dominant Allele for the population. The HbA/HbS gene will thrive because it helps in the fight against Malaria‚ turning a typically negative trait into an advantage. The Homozygous Recessive will disappear from the population because either way it has a fatal disease. The Homozygous Dominant

world disease was a huge thing in the 20th century. There were many diseases that affected many people all around the world.many of them suffered or even died from it.

Only after gathering results from thousands of African Americans and looking at the correlation of the sickle cell disease in certain areas of Africa along with where malaria was found in high quantity‚ could he truly find the exact answers he needed to justify his hypothesis. Performing his tests out of pure observation or with a controlled experiment would not have gotten him the results and proof he needed. He needed

antiviral drugs have been designed to interfere with the infection process‚ they could do that by blocking the virus from their host cell.

These malaria parasites enter the liver cells and multiply‚ these liver cells eventually rapture‚

the native Africans protected themselves from the germs that caused diseases such as Smallpox and Malaria? Give specific examples cited in the film. Answer: The native Africans had developed immunity to Smallpox through repeated exposure over thousands of years and vaccinations they had developed that could provide immunity for life. In addition‚ the Africans also knew how to avoid diseases like Malaria by preventing infection. This was done by choosing to live in high‚ dry areas where the mosquitoes
