From Genome Blogger Diogenes. Here’s the details:
I’m very interested in samples from Europe, like Ireland (particularly the Western part), UK (all, but more Cornwall, Wales, Scotland Highlands), Finland, Scandinavia (especially Norway), Iceland, Switzerland, Austria (especially Tirol), Slovakia, Carpathians in general (regions of Romania, Poland, etc), Germany, Ukraine, Iberia and France (especially Alps, Massif Central, Pyrenees) with regional identification. Plus people from the Americas with significant known Amerindian ancestry (tribe or regional-tagged please). Also any mountain or island region in the world not represented in my current sample. I know I’m naming several regions with few participants in other projects. So I’m not even mentioning Madagascar, Sami, Indonesia, or Australian samples with known or possible aboriginal origin.
I need to do a post rounding up a list of Genome Bloggers and also pointers to data sources soon. Also, in case you haven’t kept track of it, Zack Ajmal has been pruning problematic individuals from the various data sets he’s been collecting (e.g., duplicates, very close relatives, etc.).

Over at Harappa Simranjit has been allowing Zack to post his isopleth maps of the frequencies of ADMIXTURE components by region. He now has his own blog, The Jatt Gene. On unrelated note, does anyone know of an easy way to generate isopleth maps which is open source?
Comments Off on Mapping ADMIXTURE components
Dienekes, David, and Zack, have now integrated the insight from Reconstructing Indian History that the programs which infer population structure, such as STRUCTURE, frappe, and ADMIXTURE, can produce ancestral components which are themselves actually stabilized hybrids. In particular the “South Asian” component in many of these analyses may be an ancient admixture between a European-like population, “Ancestral North Indians,” and an indigenous population with marginally greater affinities to East Asians than Europeans, “Ancestral South Indians.”
Here are the posts of interest:
- Ancestral North Indian – Ancestral South Indian (ANI/ASI) inferred proportions for South Asian members
- Reconstructing the Ancestral North Indian (ANI) genome
- Dienekes on ANI/ASI
