Dodecad K10a
Dodecad K10a — Modern 10‑component ancestry model.
Quickly quantify your autosomal ancestry across ten reference clusters (Palaeoafrican, South Asian, West Asian, Southeast Asian, Sub‑Saharan, Atlantic_Baltic, Red Sea, East Asian, Mediterranean, Siberian). Ideal for genealogy enthusiasts and researchers who want a compact, interpretable snapshot of regional affinities and admixture patterns. Use as a clear starting point for deeper genetic investigation.

About This Calculator
Dodecad K10a — Modern 10‑Component Admixture Calculator
This calculator estimates the proportional ancestry of a DNA sample using a modern 10‑component model derived from global reference populations. It analyzes autosomal genotype data to report how much of an individual's genetic makeup aligns with each of the following reference clusters: Palaeoafrican, South Asian, West Asian, Southeast Asian, Sub‑Saharan, Atlantic_Baltic, Red Sea, East Asian, Mediterranean, and Siberian.
Who it's for:
- Genetic genealogy enthusiasts seeking clearer regional affinities
- Population geneticists and students exploring comparative models
- Anyone curious about broad continental and subcontinental ancestry signals
What you get:
- A quantitative breakdown (percentages) across 10 interpretable genetic components
- Clear signals of admixture events and affinities (e.g., Atlantic_Baltic vs Mediterranean)
- Clues about recent vs deep ancestral contributions based on component patterns
Context and interpretation: This model is a compact representation of modern genetic diversity. Each component corresponds to an allele‑frequency cluster that reflects historical population structure and migrations (for example, Red Sea may track Northeast African/Arabian links, Atlantic_Baltic captures northwestern European/Siberian interplay). The labels are heuristic: they summarize complex histories and are best interpreted as regional affinities rather than precise ethnic labels.
Why it’s valuable:
- Provides an accessible, reproducible snapshot of ancestry with balanced geographic coverage
- Useful as a starting point for deeper analyses (haplogroups, local ancestry, formal tests)
- Helps users contrast competing historical scenarios and visualize admixture proportions quickly
Limitations and best practices:
- Not a definitive report of identity — results depend on reference sampling and clustering
- Combine with genealogical records and other genetic tools for robust conclusions

Reference Populations
The populations used as genetic references in this calculator
10 Reference Populations
Palaeoafrican: Represents ancient African ancestry, encompassing diverse early human populations on the African continent.
South Asian: Encapsulates populations from the Indian subcontinent, including India, Pakistan, Bangladesh, Nepal, and Sri Lanka.
West Asian: Refers to populations from the regions in the Near East, including parts of the Middle East and Caucasus.
Southeast Asian: Encompasses populations from countries like Thailand, Vietnam, Indonesia, and the Philippines.
Sub-Saharan: Represents populations from regions south of the Sahara desert, characterized by diverse ethnic groups and rich cultural histories.
Atlantic_Baltic: Covers populations from northwestern Europe, including areas around the Atlantic Ocean and the Baltic Sea.
Red Sea: Involves populations from the areas surrounding the Red Sea, often considered as part of the African and Arabian territories.
East Asian: Includes populations from China, Japan, Korea, and neighboring regions with shared historical and cultural heritage.
Mediterranean: Refers to populations from the Mediterranean Basin, encompassing parts of Southern Europe, North Africa, and the Levant.
Siberian: Represents populations from Siberia, known for its indigenous groups and vast, diverse ethnicities.
Continental Groups:
- Africa: Palaeoafrican, Sub_Saharan, Red Sea
- Asia: South Asian, West Asian, Southeast Asian, East Asian, Siberian
- Europe: Atlantic_Baltic, Mediterranean
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 10 carefully selected modern populations as references, allowing for a detailed breakdown of your genetic heritage.
How It Works
- Your DNA is compared to 10 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
