Why are African Americans more likely to have sickle cell anemia than other American groups? - what is anemia more condition_symptoms
Why do people do such act, is a question of racism?
It has been shown that this disease is more common among the black population.
taken from a website:
Researchers have discovered that the gene for sickle cell anemia, particularly prevalent in areas of Africa most affected by malaria. In some regions up to 40 per cent of the population carries at least one gene for HBS.
It seems that in these areas, firms have been HbS natural selection, because the train transmits a certain resistance to malaria. Their red blood cells with abnormal hemoglobin, tend to sickle when infected by the malaria parasite. These infected cells can flow through the spleen, have made the sacrifice because of their sickle shape - and the parasite is eliminated with them.
Scientists believe that the gene for sickle cell disease appeared and disappeared in the population several times, but was permanently established after a particularly vicious form of transfer of disease from animals to humans in Asia, Middle East and Africa.

Malaria is widespread in parts of Africa, and is highly virulent in these places. It is so deadly, he became a great power of adaptation in the population living in these places. Sickleing feature was that the adaptation and provides some protection against the disease. The problem is that protection is available if the line comes from a single parent household. When property is inherited from both parents, anemia occurs.

In my class on human evolution has long been my teacher said something that began to sickle cell disease in Italy and emigrated to the rest of the Mediterranean, Africa and India.
So continue to answer your question why.
Developed 1 - sickle cell anemia, because it provides resistance to malaria.
2 - The Sickling traveled south and east by the propagation between the groups
3 - Malaria is most common in Africa, so that the most common in people of African descent.

Because of genetics, hemoglobin of African-Americans are more than "corrupt" (an extra) hop in the chain of amino acids and causes diseases.
But to compensate for this, is better than the white rate; D
- As someone said prevelent protection against malaria in Africa and because we are African-Americans ...
For the same reason that Americans euro CF skin cancer than other Americans ... Genetics
How do you know? Statistics Really? They are not 100% correct.
whered you this, Satistics always wrong
