What are People with Anemia resistant to?
Sickle cell anemia comes as the result of having two sickle cell chromosomes. One sickle cell chromosome makes people resistant to malaria. Unfortunately when people have two sickle cell chromosomes they can get sickle cell anemia. That makes it difficult for their blood to carry oxygen and under certain conditions makes their blood clump. The disease can be deadly. Drugs can help. It probably makes that person resistant to malaria. The sickle cell trait evolved in various places around the world where malaria is common such as Africa and Greece.
Where in the world are the most cases of Malaria and Sickle Cell anaemia?
Malaria is common in topical ad subtropical zones. The malaria has selected the people with sickle cell anaemia. Although person with sickle cell anemia can have malaria, the carrier, or the person with sickle cell trait is resistant to malaria.
What are people with sickle cell resistant to?
Sickle cell anemia provides resistance to malaria - it is ideal for many people in Africa that live in mosquito rampant areas.
Individuals heterozygous for sickle-cell anemia appear normal and are resistant to what disease?
malaria
Who are resistant to malaria?
People with sickle cell disease, or who carry sickle cell trait, are said to be resistant to malaria.
According to our readings the only human adaptation to malaria is sickle-cell anemia?
the only human adaptation to malaria is sickle-cell anemia true?
Why sickle cell anemia resistance malaria?

Are people with Hemophilia prevented of getting Malaria?
No, hemophilia does not confer an advantage against malaria. People with sickle-cell anemia do have an immunity, of sorts.
Individuals with malaria have a better chance of surviving if they have which type of anemia?
Sickle-cell anemia
Why sickle anemia not infected by malaria?
People with sickle cell anemia possess a genetic mutation that causes their red blood cells to assume a crescent or sickle shape. This altered shape makes it more difficult for the malaria parasite, Plasmodium, to thrive and reproduce within these cells. Additionally, the sickle cells are more likely to be destroyed by the body, reducing the number of cells available for the malaria parasite to infect. As a result, individuals with sickle cell anemia have a higher resistance to malaria compared to those with normal hemoglobin.
Which individuals have the greatest fitness in an area where malaria is common?
Individual homozygous for the sickle cell anemia allele
Why is sickle cell anemia beneficial in some regions but harmful in others?
Sickle cell anemia is beneficial in regions with high malaria prevalence because it provides some degree of protection against the disease. In these regions, individuals with sickle cell trait have a survival advantage in fighting off malaria compared to those without the trait. However, in regions where malaria is not prevalent, the negative health effects of sickle cell anemia, such as anemia and organ damage, outweigh any potential benefits.
