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.

How are sickle cell anemia and maleria the same?
They are definitely not the same. If you are looking for an answer to WHY sickle-cell anaemia is BENEFICIAL to those with malaria then follow this link,What_is_the_benefit_of_sickle_cell_anemia_to_Africans_with_malaria
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.
What is One pleiotropic affect of sickle cell syndrome?
One pleiotropic effect of sickle cell syndrome is increased resistance to malaria. The genetic mutation that causes sickle cell disease also confers some protection against malaria infection, as the malaria parasite has difficulty surviving in the altered red blood cells of individuals with sickle cell trait.
Why does sickle cell anemia persist?
Primarily because of the same reason why any of us still persists, because even those people can reproduce. And it has been proven that people who has sickle cell anemia are immune to malaria.
Heterozygous persons with one sickle cell allele and one normal allele also show resistance to?
malaria. This resistance is due to the fact that the sickle cell trait confers some protection against the malaria parasite, Plasmodium falciparum, making individuals less susceptible to severe malaria infections.
Do individuals who are heterozygous for sickle-cell anemia have a greater resistance to malaria?
Yes, individuals who are heterozygous for sickle-cell anemia have a greater resistance to malaria due to the presence of the sickle cell trait which makes it more difficult for the malaria parasite to survive in the red blood cells.
Is sickle cell anemia recessive or dominant?
Sickle cell anemia is an autosomal recessive disease. Carriers have sickle cell trait, which confers resistance 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?
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.
In which area in Africa would you expect the sickle-cell hemoglobin gene to be the most common?
The area with the most malaria. Sickle-cell confers resistance against malaria, and so you'd expect populations in the most malaria heavy zones to have the highest prevalance of sickle-cell anemia.
What are survival values of sickle cell anemia?
A single copy of the gene results in a person who is unlikely to develop full-blown sickle-cell anaemia, but has a strong resistance to malaria.
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.
Are people with sickle cell anemia resistant to malaria?
No they are generally resistant to malaria
Individuals with malaria have a better chance of surviving if they have which type of anemia?
Sickle-cell anemia
What are good sources for researching malaria and sickle-cell anemia?
www.cdc.gov
What is the disease that attacks only negroes?
Malaria or sickle-cell anemia?
Is sickle cell common?
Sickle cell anemia is found in approximately 1 in 5000 people. It is mostly found in people from Sub-Saharan Africa do to the nature of the disease providing resistance to malaria.
