This thread could equally well be in Biology, but since genetics and hereditability have figured so prominently in the various IQ threads in this sub-forum, I feel it would a good place, and perhaps a useful resource. L. Luca Cavalli-Sforza, Paolo Menozzi, and Alberto Piazza published the classic work in the field in 1994: "The History and Geography of Human Genes". The result of over a decade of detailed work, it was nonetheless compiled before the human genome had been mapped. Since then, Cavalli-Sforza, Piazza and others have been involved in getting the ambitious "Human Genome Diversity Project " off the ground. What is it? " The HGD Project is an effort by anthropologists, geneticists, doctors, linguists, and other scholars from around the world to document the genetic variation of the human species worldwide. This scientific endeavor is designed to collect information on human genome variation to help us understand the genetic makeup of all of humanity and not just some of its parts. The information will also be used to learn about human biological history, the biological relationships among different human groups, and may be useful in understanding the causes of and determining the treatment of particular human diseases." I do not know its current status. The http://www.sanger.ac.uk/genetics/humgen.shtml [Broken] has several projects underway to study variation in the human genome, with disease association and variable response to environmental factors and drugs as key areas. Perhaps other PF members would like to add details of similar big projects that they know of.
