About This Calculator

**Tolan K13 M2 — Modern 13-way Admixture Calculator** This calculator analyzes an individual's genome to estimate proportions of ancestry across 13 modern reference populations. It is built for worldwide use and designed to give both casual users and researchers a clear, interpretable breakdown of recent ancestry components. Outputs are expressed as percentage contributions to reflect likely genetic input from each region over the last few thousand years. What it analyzes - Genome-wide single-nucleotide variation compared to 13 reference clusters - Relative affinity to modern population profiles (not ancient samples) - Patterns consistent with recent admixture, migrations, and regional gene flow Reference populations - A: West Europe - B: East Europe - C: South Mediterranean - D: Caucasus - E: Arabia - F: Siberia - G: Central Asia - H: India - I: South-East Asia - J: West Africa - K: East Africa - L: Oceania - M: East Asia Who it's for - Individuals exploring family origins and migratory background - Genetic genealogy hobbyists seeking regional resolution - Researchers needing a compact modern admixture profile for comparative work Insights you can gain - Proportional ancestry estimates that highlight major regional contributors - Detection of expected and unexpected admixture signals (e.g., Eurasian–African mixtures) - Context for genealogical records and historical migration hypotheses Historical and genetic context This model emphasizes modern population structure shaped by historic migrations, trade networks, and recent gene flow rather than deep Paleolithic lineages. It is most informative for events in the Holocene and late prehistory through modern times. Why it’s valuable - Clear, reproducible breakdown into 13 interpretable components - Useful starting point for deeper analyses (local ancestry, haplogroups) - Balances resolution and interpretability for a global audience Limitations - Reference clusters are simplifications of continuous human

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 13 carefully selected modern populations as references, allowing for a detailed breakdown of your genetic heritage.

How It Works

Your DNA is compared to 13 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
