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 Us

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
