Population Genetics
Risch has condicted significant work on the nature of human differences on a geographical scale. For instance, he used social and genetic data to analyse genetic admixture from White, African, and Native American ancestry in Puerto-Rico, as well as relating this to geographical variation in Social status
Risch considers that genetic drift is a more compelling explanation for the carrier frequency of lysosomal storage diseases in Ashkenazi Jews than heterozygote advantage, in light of analysis of the results of recent genetic testing by his collaborators and himself.
After mapping torsion dystonia by linkage disequilibrium (LD) analysis he found it was genetically dominant and was a founder mutation. Other work has focused on the genetic basis of Parkinson's disease, hemochromatosis, multiple sclerosis, diabetes, autism, epilepsy and hypertension.

Famous quotes containing the word population:
“[Madness] is the jail we could all end up in. And we know it. And watch our step. For a lifetime. We behave. A fantastic and entire system of social control, by the threat of example as effective over the general population as detention centers in dictatorships, the image of the madhouse floats through every mind for the course of its lifetime.”
—Kate Millett (b. 1934)
