Description

Tolan K18 M4 is a modern, global admixture calculator that estimates an individual's ancestral components using 18 curated reference populations spanning Europe, the Mediterranean, Africa, the Near East, Central and South Asia, and East Asia. Designed for genealogists, population geneticists, ancestry enthusiasts and anyone curious about their genetic origins, this tool translates genotype data into an intuitive breakdown of likely regional contributions and historical affinities. What it analyzes: Tolan K18 M4 compares a user’s SNP profile against eighteen comparative clusters — including Atlantic and various European subgroups, Mediterranean and Near Eastern groups, multiple African and Central Asian references, and East and Southeast Asian components — to quantify proportional ancestry and highlight likely source regions. Results emphasize relative contributions rather than absolute labels, helping users interpret complex admixture patterns produced by centuries of migration, trade and population contact. Insights you can gain: Users receive a detailed proportional profile, clarity on subtle north-south or east-west gradients, and signals of historical events such as Steppe-related or Mediterranean influences. For researchers, the calculator supports hypothesis testing about admixture timing and source populations; for individuals, it provides context for family histories, migration narratives, and regional heritage. Historical and genetic context: The reference set reflects major prehistoric and historic population corridors — Atlantic and Central European lineages, Steppe and Caspian influences, Anatolian and Persian-Gulf connections, North African and Equatorial African components, and South/Central Asian and East Asian gradients. This breadth helps reveal deep and recent admixture alike. Why it’s valuable: By combining broad geographic coverage with interpretable output, Tolan K18 M4 delivers reliable, actionable ancestry estimates. It balances scientific

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

How It Works

Key Points

Your DNA is compared to 18 reference populations
Modern populations are used as references
Results show your genetic similarity to these populations

Understanding Your Results

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

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