Strictly speaking, there's no such thing as "races"... at least as far as humans are concerned.
So I voted "Other". My ethnicity is German though (for the most part).
Right, which is why blacks are not more prone to get sickle cell anemia.
Please, everybody with a basic formation in biology knows than human races doesn't exist. Blacks are more prone to get sickle cell anemia, true. But not because they are blacks. A genetic mutation happened someday on an african black and the mutation followed some of his descendants. Blacks are more prone to it since they are more likely to select black persons to reproduce. If they were not more likely to choose black people, sickle cell anemia would be more equally distributed between skin colors.
And white persons have other sicknesses like that. Less obvious, since more genetic mixing happened in Europe and in America between different ethnic origins of white persons.
