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 often doese sickle cell anemia occur in the population?
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.
How is it possible for only some races to have certain diseases or deformities like Sickle-Cell Anemia for African-Americans and Head Lice for Caucasians?
Some diseases are the result of adaptations to an environment. As it turns out, Sickle Cell Anemia is an adaptation to Malaria. If a person has a single copy of the Sicke Cell gene, he or she is protected against Malaria. If he or she has NO copies of the gene, he or she will die if exposed to Malaria. If he or she has two copies of the gene he or she will die from Sickle Cell Anemia. Malaria was fatal to pretty much everyone. The genetic mutation allowed about half of the population of the region to live. Today, we no longer have the threat from Malaria so now Sickle Cell Anemia becomes the problem.
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 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.
When was sickle cell anemia discovered?
Sickle cell anemia was discovered in the 1870's and carried many names, but 1922 it was officially named sickle cell anemia.
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
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.
What is the disease that attacks only negroes?
Malaria or sickle-cell anemia?
What are good sources for researching malaria and sickle-cell anemia?
www.cdc.gov
What genetic disorder can be beneficial in its heterozygous form?
Sickle Cell Anemia, in it's heterozygous form it does not present as the disease and it gives the carrier resistance to malaria.
