Admixture Calculator

LM Genetics K12

**LM Genetics K12 — 12‑way global admixture snapshot** A clear, accessible autosomal calculator that partitions your DNA into twelve modern reference components (Amerindian, European, African, Siberian, SE‑Asian, Kalash‑Caucasian, SW‑Asian, South‑Indian, Papuo‑Melanesian, Khoisan). Ideal for global users, genealogists, and researchers seeking a concise overview of multi‑regional ancestry and admixture signals. Interpret with historical context and additional analyses.

About This Calculator

**LM Genetics K12 — Global 12‑way Admixture Calculator** This calculator decomposes a DNA sample into twelve modern reference components to reveal broad ancestry signals and recent admixture patterns. It analyzes autosomal variation and reports proportional contributions from: Central‑Amerindian, South‑Amerindian, NE‑Euro, SW‑Euro, West‑African, Khoisan, Siberian, SE‑Asian, Kalash‑Caucasian, SW‑Asian, South‑Indian, and Papuo‑Melanesian. **Who it’s for** - Global users curious about multi‑regional ancestry - Genealogists and hobby geneticists seeking comparative breakdowns - Researchers and students needing a clear, 12‑component overview **What you learn** - Percent contributions of each reference population to your autosomal profile - Relative affinities that reflect recent and deeper admixture events - Geographic and historical cues (e.g., Eurasian steppe, Austronesian signal, African and Amerindian traces) **Context and interpretation** The K12 model is a modern, simplified framework: components represent contemporary reference clusters rather than single ancient populations. Signals can reflect complex histories—migrations, trade, and population blends—so a given percentage indicates genetic affinity, not a precise cultural or ethnic label. Overlap between neighboring groups and shared ancestry older than the resolution of this model can blur distinctions. **Why this calculator is valuable** - Provides a clear, comparable 12‑way snapshot useful for cross‑sample comparisons and exploratory analysis - Helps identify unexpected regional affinities and guides deeper investigation with targeted tests or historical research - Balances accessibility for non‑specialists with informative output for experienced users **Caveats** Not a clinical test: interpretations should be combined with genealogical records and additional genetic analyses. Results depend on reference sampling and model assumptions. Use LM Genetics K12 as a practical, educational tool to visualize

Reference Populations

The populations used as genetic references in this calculator

12 Reference Populations

Continent: Americas

Central-Amerindian: Indigenous peoples of Central America, sharing genetic components from pre-Columbian times.
South-Amerindian: Indigenous populations of South America, reflecting ancient Native American ancestry.

Continent: Europe

NE-Euro: Populations from Northeastern Europe, including Scandinavians and Balts.
SW-Euro: Southwestern European peoples, such as Iberians and Southern French.

Continent: Africa

West-African: Groups from West Africa, known for distinct genetic lineage and rich cultural history.
Khoisan: Indigenous to Southern Africa, known for their unique click languages and hunter-gatherer culture.

Continent: Asia

Siberian: Native populations of Siberia, with ties to Arctic and subarctic regions.
SE-Asian: Ethnic groups from Southeast Asia, reflecting diverse cultures and genetic backgrounds.
Kalash-Caucasian: Ethnic groups from the Hindu Kush region, including the unique Kalash people.
SW-Asian: Populations from Southwestern Asia, including Middle Eastern ethnic groups.
South-Indian: Inhabitants of Southern India, marked by Dravidian languages and robust cultural traditions.

Continent: Oceania

Papuo-Melanesian: Indigenous peoples of Papua New Guinea and the broader Melanesian region, known for diverse languages and cultures.

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

How It Works

Your DNA is compared to 12 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
