Admixture Calculator

Tolan K7 M1

**Tolan K7 M1 — Modern 7‑way admixture** A clear, accessible K=7 admixture calculator comparing your genotype to seven global reference clusters (North‑Euro, Mediterranean, Caspian‑Sea, N‑Africa & Middle‑Eastern, Africa, SE‑Asia, NE‑Asia). Ideal for anyone seeking a concise breakdown of regional ancestry proportions, historical context, and a practical baseline for further genealogical or population‑genetic exploration.

About This Calculator

**Tolan K7 M1 — Global 7‑way Admixture (Modern Era)** This calculator estimates the proportional ancestry of an individual against seven modern reference clusters. Using a K=7 model (M1), it compares your genotype to curated reference populations and returns percentages for: **North‑Euro, Mediterranean, Caspian‑Sea, N‑Africa & Middle‑Eastern, Africa (Sub‑Saharan), SE‑Asia, and NE‑Asia**. What it analyzes - Genome‑wide allele frequencies to infer relative contributions from seven broad regional components. - Signals that reflect both recent gene flow (within the past few hundred years) and deeper population structure shaped by migrations and isolation. Who it’s for - Individuals curious about their genetic heritage worldwide. - Amateur and professional genealogists seeking population‑level context. - Researchers and students needing a clear, interpretable K=7 baseline for comparative analyses. Insights you can gain - A clear numeric breakdown of continental and regional ancestry proportions. - Clues about likely historical interactions (e.g., Eurasian steppe influence, Mediterranean admixture, African or East Asian inputs). - A starting point to explore migration routes, admixture events, and regional genetic continuity. Historical and genetic context Each reference cluster represents broad, real‑world population patterns: North‑Euro (northern/central Europe and steppe‑derived signals), Mediterranean (southern Europe and Anatolia), Caspian‑Sea (Caucasus/Iranian plateau influences), N‑Africa & Middle‑Eastern (Levantine and Maghreb affinities), Africa (sub‑Saharan ancestries), SE‑Asia (Southeast Asian and Austronesian links), and NE‑Asia (East Asian/Siberian heritage). These components reflect millennia of migrations — from prehistoric expansions to recent trade and conquest — but are simplified models of complex history. Why it’s valuable - Fast, intuitive overview of where your genetic ancestry is most similar today. - Useful baseline for comparing results

Reference Populations

The populations used as genetic references in this calculator

7 Reference Populations

North-Euro
- Description: Populations originating from Northern Europe, characterized by a diverse blend of Germanic, Celtic, Slavic, and other European ancestries.
Mediterranean
- Description: Encompasses populations along the Mediterranean Sea, including Southern Europe, the Levant, and North Africa, marked by historical intercultural trade and mixing.
Caspian-Sea
- Description: Populations around the Caspian Sea, including Central Asians and Caucasians, known for their Turkic and Persian influences.
N-Africa&Middle-Eastern
- Description: Covers North African populations west of Egypt and Middle-Eastern populations, rich in Arab, Berber, and Semitic ancestries.
Africa
- Description: Includes Sub-Saharan African populations, showcasing a variety of ethnic groups with deep genetic diversity.
SE-Asia
- Description: Southeast Asian populations, including Indonesians, Thais, and Filipinos, marked by Austronesian and Sino-Tibetan ancestries.
NE-Asia
- Description: Populations in Northeastern Asia, such as the Chinese, Japanese, and Koreans, known for their Han Chinese and other indigenous Asian influences.

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

How It Works

Your DNA is compared to 7 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
