Yes, but the mutation happened many many thousands of years ago. It has been passed on through all these generations because the same gene that causes sickle cell anemia in a person that inherits two copies of the gene also causes resistance to the malaria parasite in a person that inherits only one copy of the gene.
In areas of the world where malaria is a common disease, the resistance to it is a stronger selective advantage than sickle cell anemia is a selective disadvantage; so the gene becomes very common in those populations.
Sickle cell anemia is caused by point mutations. It affects the codon that codes for glutamic acid and changes it into valine.

An example of point-mutation is sickle-cell anemia. Sickle-cell disease is hereditary.

Yes, Sickle Cell-Anemia is a genetic condition that is passed down from one generation to the other.
sickle-cell anemia.
Sickle Cell Anemia is Autosomal Recessive. It arises from a mutation on the beta-globin gene of chromosome 11. Because Sickle Cell Anemia is an example of incomplete dominance, a person has the disease if they have two mutated beta-globin genes but only has the trait (is a carrier) if they have only one mutated beta-globin gene.
pooo
No single mutation is responsible for this disease. It just happens by abnormality in the red blood cells. It affects the hemoglobin.
While technically there are more than one, the main one by far is sickle cell anemia.
Sickle cell anemia is an example of a cell mutation that can be inherited.
Sickle cell anemia -yes it is hereditary
Yes, and this is the only way to get sickle cell disease or sickle cell anemia. Sickle cell (both the milder "disease" form and the more severe "anemia" form) are caused by an inherited mutation in a protein that helps form the red blood cells - the defect results in red blood cells that are shaped like crescents or sickles, which is how the disease gets its name.
