About This Calculator

**Global Ancestry K25 (Modern, without Jewish populations)** This calculator estimates an individual's autosomal ancestry as proportions across a 26‑component modern reference panel (K25). It quantifies how much genetic affinity you share with geographically and historically informed populations from Africa, Europe, Asia, the Middle East, and Oceania. Notably, this version excludes specific Jewish reference groups to focus on broad regional clusters. What this analyzes - Autosomal admixture proportions against 26 modern reference populations (e.g., East_European, Anatolia_Caucasus_Iranian_Plateau, Bengal, West_African, Oceania). - Relative genetic affinity reflecting recent and deep population history rather than strict “labels.” Who it’s designed for - Genetic genealogy enthusiasts seeking finer regional resolution. - Population geneticists and students needing a modern multi‑regional baseline. - Anyone curious about ancestral composition across Eurasia, Africa, and Oceania. Insights you can gain - Proportions of ancestry tied to major geographic and historical planes: Near Eastern farmer and Caucasus-related signals, Steppe/north‑central Asian influences, South and Southeast Asian components, African regional distinctions, and Oceanian signatures. - Clues about migration, admixture, and recent regional contact when combined with dates or family history. Historical and genetic context This panel reflects modern population structure shaped by events such as post‑glacial recolonization, the Neolithic transition from Anatolia and the Iranian plateau, Bronze Age Steppe movements into Europe and South Asia, maritime expansions in Southeast Asia and Oceania, and long‑distance dispersals across Africa and Eurasia. Why it’s valuable - Offers fine-grained, interpretable components for comparative analyses. - Useful as a cross‑check against other calculators and for identifying unexpected admixture signals. Caveats - Results depend on reference sampling and mode

Understanding Admixture Analysis

Learn how admixture calculators work and how to interpret your results

What is Admixture Analysis?

Admixture analysis is a method used to estimate your genetic ancestry by comparing your DNA to reference populations from around the world. Think of it as creating a recipe of your genetic makeup, where the ingredients are different ancestral populations.

This calculator uses 25 carefully selected modern populations as references, allowing for a detailed breakdown of your genetic heritage.

How It Works

Your DNA is compared to 25 reference populations
Modern populations are used as genetic references
Results show your genetic similarity to these populations
More accurate with a diverse reference panel

Understanding Your Results

Your results will show percentages of genetic similarity to these reference populations. Remember these important points:

Results reflect genetic similarity, not direct ancestry
Modern populations are used as references
Percentages indicate relative genetic contribution
Results are estimates based on available reference data
