Admixture Calculator

Dodecad Globe 13

**Dodecad Globe 13** is a modern, global admixture calculator that estimates your ancestry as proportions from 15 reference populations (African, Eurasian, Amerindian, Australasian, Arctic and regional subgroups). Ideal for genealogists, students, and researchers, it reveals regional affinities and historical admixture signals while providing a nuanced, comparative view of your genetic heritage.

About This Calculator

**Dodecad Globe 13 — Modern global admixture calculator** Dodecad Globe 13 estimates an individual's genetic ancestry as proportions from 15 globally distributed reference populations. It compares your genotype against allele-frequency clusters representing major continental and regional groups to give a readable, comparative profile of ancestral components in a modern, world-wide context. **What this calculator analyzes** - Proportional ancestry contributions from: Siberian Amerindian, African, West African, Palaeo African, East African, Asian, East Asian, South Asian, Southwest Asian, West Asian, European, Mediterranean, North European, Australasian, and Arctic. - Relative affinities created by shared genetic drift and allele-frequency patterns across populations. **Who it's designed for** - Genealogy enthusiasts and curious individuals exploring personal ancestry. - Students and educators illustrating patterns of human diversity. - Population geneticists and researchers seeking a compact comparative view. **Insights you can gain** - Estimated percentage ancestry from each reference cluster. - Signals of historical migrations and admixture (e.g., Eurasian steppe, African dispersals, Australasian or Arctic affinities). - Fine distinctions among nearby Eurasian components (North European vs Mediterranean vs West Asian) and among African regional clusters. **Historical and genetic context** Human genetic variation reflects repeated migrations, isolations, and admixture events — out-of-Africa dispersals, the peopling of the Americas, Holocene expansions across Eurasia, and maritime movements into Australasia and the Arctic. Dodecad Globe 13 places your genome within that tapestry using modern comparative samples. **Why this calculator is valuable** - Global scope with 15 informative reference clusters offers nuanced results beyond broad continental labels. - Useful as an interpretive tool alongside documentary genealogy, archaeology, and other genetic evidence.

Reference Populations

The populations used as genetic references in this calculator

13 Reference Populations

Siberian Amerindian

Description: Populations native to Siberia and American indigenous peoples sharing genetic connections. Influences from ancient migrations across the Bering Strait.

African

West African

Description: Populations from West Africa, known for rich genetic diversity and history predating colonial times.

Palaeo African

Description: Ancient African populations, providing insight into early human evolution and migration within the continent.

East African

Description: Diverse ethnic groups from eastern Africa, encompassing Swahili coast cultures and the Great Lakes region.

Asian

East Asian

Description: Populations from China, Korea, Japan, and Mongolia, with shared cultural and historical backgrounds.

South Asian

Description: Encompasses Indian, Pakistani, Sri Lankan, and Bangladeshi ethnicities with a long history of trade and cultural exchange.

Southwest Asian

Description: Refers to Middle Eastern populations, with significant historical civilizations such as Mesopotamia and the Levant.

West Asian

Description: Encompasses populations from regions like Iran and the Caucasus, historically significant for ancient empires.

European

Mediterranean

Description: Coastal populations of Southern Europe, North Africa, and the Near East, diverse due to extensive maritime trade.

North European

Description: Includes populations from Northern Europe like Scandinavia, characterized by fair skin and diverse linguistic roots.

Australasian

Description: Encompasses Aboriginal Australians and Pacific Islanders, who have unique genetic markers and deep-rooted indigenous traditions.

Arctic

Description: Populations from the Arctic regions, such as Inuit and Saami, adapted to cold climates with specialized cultural practices.

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

How It Works

Your DNA is compared to 13 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
