Your problem here is how do you define population? I'm not much of a population geneticist, but I have a small amount of biological anthropology and it's my understanding that to talk of the "African population" is simplistic at best. Some one else with more background want to give a better informed answer? - Neal

Suggest you start with the human genome diversity project here: http://www.stanford.edu/group..., but also note the strong criticisms of this approach, well-articulated here: http://www.hgalert.org/topics.... - Maxine
