Admixture Calculator

MDLP K7

**MDLP K7 — Modern 7‑way global ancestry profile** A clear, interpretable admixture calculator that breaks a genotype into seven regional components: Scandinavian, Volga_Region, Altaic, Celto_Germanic, Caucassian_Anatolian_Balkanic, Balto_Slavic, and North_Atlantic. Designed for genealogists, researchers and curious users, it reveals major ancestral influences using modern reference populations while emphasizing population‑level inference, not individual identity.

About This Calculator

**MDLP K7 — Modern 7‑way Global Admixture Calculator** This calculator decomposes a modern human genotype into seven broad, interpretable ancestry components derived from worldwide reference populations. It quantifies the proportional genetic contribution from: **Scandinavian**, **Volga_Region**, **Altaic**, **Celto_Germanic**, **Caucassian_Anatolian_Balkanic**, **Balto_Slavic**, and **North_Atlantic**. Results are given as percentage shares that reflect how closely an individual's allele frequencies match each regional signature. Who it's for: - Genetic genealogy enthusiasts and family historians - Population geneticists and anthropologists seeking a clear, comparative breakdown - Anyone curious about continental and regional ancestry patterns in a modern context What you learn: - A concise 7‑component profile showing major ancestral influences across Europe, West Asia and parts of Central/East Asia - How your genetic makeup compares to broad historical population groupings and migration corridors - Insights useful for contextualizing family histories, regional affinities, and large‑scale demographic events Historical & genetic context: - The components are proxies informed by modern reference samples and reflect long‑term processes — Neolithic farmer expansions, Bronze Age migrations, steppe and Altaic movements, and coastal Atlantic/Scandinavian interactions. - Labels (e.g., "Caucassian_Anatolian_Balkanic") aggregate related signatures (Anatolian farmers, Caucasus ancestry, Balkan continuity) useful for broad interpretation rather than pinpointing single ancestral towns. Why this calculator is valuable: - Offers an accessible, stable 7‑way framework for comparing individuals and populations globally - Balances resolution and clarity: enough components to see major historical signals, few enough to remain interpretable Limitations: - Components are statistical proxies from modern populations; they do not represent discrete ancestral tribes or direct personal

Reference Populations

The populations used as genetic references in this calculator

7 Reference Populations

Scandinavian
- Populations from Northern Europe, including countries like Sweden, Norway, Denmark, and Finland.
Volga_Region
- Populations around the Volga River, including ethnic groups like the Mari, Mordvins, and Tatars in Russia.
Altaic
- Populations from Central Asia and Siberia, often associated with Turkic, Mongolic, and Tungusic groups.
Celto_Germanic
- Populations from Central and Western Europe, encompassing Celtic nations (e.g., Ireland, Scotland, Wales) and Germanic regions (e.g., Germany, Netherlands).
Caucassian_Anatolian_Balkanic
- Diverse populations from the Caucasus region (e.g., Georgians, Armenians), Anatolia (modern-day Turkey), and the Balkans (e.g., Greeks, Bulgarians).
Balto_Slavic
- Populations from Eastern Europe, including Baltic states (e.g., Lithuania, Latvia) and Slavic countries (e.g., Poland, Russia).
North_Atlantic
- Populations from nations bordering the North Atlantic Ocean, particularly coastal Western Europe and the British Isles.

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
