Dienekes points me to a new paper, European Population Genetic Substructure: Further Definition of Ancestry Informative Markers for Distinguishing Among Diverse European Ethnic Groups. You’ve seen this song & dance before: Population substructure in Japan Population substructure of Mexican Mestizos European population substructure Genetic Map of East Asia The genetics of Fenno-Scandinavia Finns as European…

An ancestry informative marker set for determining continental origin: validation and extension using human genome diversity panels: Results In this study, genotypes from Human Genome Diversity Panel populations were used to further evaluate a 93 SNP AIM panel, a subset of the 128 AIMS set, for distinguishing continental origins. Using both model-based and relatively model-independent…

I still remember when L. L. Cavalli-Sforza’s The History and Geography of Human Genes was a candle in the dark, illuminating human history with slivers of genetic data laboriously gathered and analyzed over decades. We’ve come a long way. Dienekes points me to a new paper, Fine-scaled human genetic structure revealed by SNP microarrays: We…

Fine scale population substructure

Dienekes comments on the paper which showed genetic substructure among a set of Sardinian villages: The take-home lesson is that wherever gene flow is impeded, no matter how geographically close, population differentiation can be recovered with dense autosomal genotype data. Really fine-scale ancestry analysis is now possible; I suspect that a combination of geography, religion,…
