Sickle cell anemia is more prevalent in Africa due to natural selection's role in conferring a survival advantage against malaria. The sickle cell trait (carrying one copy of the gene) provides some protection against the disease, allowing individuals with the trait to survive and reproduce more successfully in malaria-endemic regions. As a result, the frequency of the sickle cell allele increases in these populations, leading to higher rates of sickle cell anemia. This illustrates how environmental pressures can shape genetic traits within a population.
What else can I help you with?
Why would natural selection act against people with sickle cell anaemia in Europe?
because people in europe have not gotten used to sickle cell anemia because it is soo rare in europe
What type of anemia is a genetic disease commonly found among of Africa descent?
Sickle cell anemia
Why do people of Mediterranean and African decent have sickle cell anemia?
Sickle cell anemia is a inherited blood disorder. This means everyone who has sickle cell has inherited it from their parents. With this in mind it means there was a key ancestor in Africa or the Mediterranean who had the first sickle cell anemia and passed it on to their descendants.
Which genetic disease is common in areas like Africa where malaria is a danger?
Sickle Cell Anemia
Which form of anemia is a genetic disorder?
It sounds like you are looking for Sickle Cell Anemia.
How do you ge sickle cell anemia?
You get Sickle-Cell Anemia by Birth,it is a genetic disorder.
What is a genetic autoimmune difficiency in which blood cells look like a sickle It is not sickle cell anemia?
sickle cell anemia
Is sickle cells disease hereditary?
Sickle cell anemia -yes it is hereditary
Is Sickle cell anemia genetic?
Yes, Sickle Cell Anemia is in fact a genetic disorder.
Is sickle cell anemia a point mutation?
An example of point-mutation is sickle-cell anemia. Sickle-cell disease is hereditary.
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.
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.
