NOTE: The model I used here SUCKS. These are NOT accurate estimates of Yamnaya ancestry in most populations.
I will make my own G25 model and publish an updated version of this article in future. Apologies for the poor information.
UPDATED: Analysis for EUROPE here: https://thuletide.wordpress.com/2021/10/28/proto-indo-european-yamnaya-corded-ware-ancestry-throughout-europe-updated-admixture-analysis-2021/
This article contains a regional breakdown of Proto-Indo-European ancestry in modern Eurasian populations, roughly divided into the groups listed below. If you think I missed any populations, let me know in the comments.
- Northwest Europe
- Northeast Europe
- Southwest Europe
- Southeast Europe
- Uralic (Finno-Ugric)
- Caucasus (Indo-European)
- Central Asian
- Eastern Iranians
- Western Iranians
- India and Pakistan
This admixture analysis uses Eurogenes Global25 Standard Calculator, which features the following ancient populations (some are modern proxies).
= Anatolian Neolithic Farmers (became Early European Farmers via migration)
= Anatolian Neolithics + Iranian Neolithics (as far as I know)
= Modern Nilotic Africans
= Ancient Ethiopians (East African)
= Modern West African
= Modern Chinese
= Neolithic Iranians
= Dzudzuanas + Ancient North Eurasians
= Bronze Age Iranians
= Neolithic Iranians + Anatolians + Levantines
= Modern Austro-Melanesians
= Bronze Age Caucasus/Middle Eastern civilization
= Caucasus Hunter-Gatherers + Anatolian Neolithic Farmers
- Levant_PPNB (Pre-Pottery Neolithic B)
= Neolithic Levant
= Fertile crescent civilization
= Paleolithic Morocco
= Modern Siberians
= Western European Hunter-Gatherer
= Modern Subsaharan Africans
In this admixture analysis, PIE ancestry is represented by Russian Yamnaya samples. Although the Corded Ware PIE population was primarily responsible for spreading Indo-European language, culture, and genetics around the world, they had additional ancestry from Early European Farmers (~20%) and Western Hunter-Gatherers (~10%). Yamnaya represents the earlier, unmixed Proto-Indo-European stock.

Ok here’s the admixture analyses….
India and Pakistan
Will update in future, let me know in comments if you want me to add any populations.
