Dodecad Globe 4
Dodecad Globe 4 — Global modern admixture calculator
A scientifically grounded autosomal admixture tool that estimates ancestry proportions across 21 global reference populations. Designed for researchers, genealogists, and curious individuals, it reveals continental and subcontinental components (European, African, Asian, Amerindian) to illuminate migration, contact, and recent admixture—presented clearly and quantitatively.

Dodecad Globe 4 — Modern Global Admixture Explorer
Dodecad Globe 4 is an autosomal admixture calculator optimized for modern, world-wide genetic datasets. It estimates proportional ancestry from 21 reference populations, spanning broad continental groups and fine-grained subregions (European, Asian, African, and Indigenous American components). The calculator analyzes genome-wide SNP data to produce a compositional portrait of an individual's recent and deep ancestry.
Who it's for:
- Researchers and population geneticists seeking a comparative global panel
- Genealogists and curious individuals exploring multi-continental roots
- Anthropologists and historians interpreting migration signatures
What you learn:
- Quantitative ancestry proportions across 21 reference populations (e.g., Northwest European, South Asian, West African, Andean)
- Biogeographic affinities and likely regional signals
- Detection of minor components that reflect historical contact (trade routes, colonization, or recent admixture)
Historical and genetic context: Human populations carry layered signatures of ancient migrations (Out of Africa, Eurasian expansions), regional founder events, and recent movements (colonization, slave trade, intercontinental migration). Dodecad Globe 4 frames your genome against this context, highlighting how continental and subcontinental ancestries combine in modern individuals and populations.
Why it matters:
- Broad, globally balanced reference set captures diversity across continents and Indigenous American subregions
- Useful for hypothesis generation about population history and recent admixture
- Presents results in an interpretable, quantitative format suitable for comparison across samples
Important caveats:
- Results are probabilistic and depend on the chosen reference panel; small component estimates are sensitive to reference composition
- Interpret outputs alongside historical, genealogical, and archaeological evidence for best inference

Was ist eine Admixture-Analyse?
Bei einer Admixture-Analyse wird Ihre genetische Ähnlichkeit geschätzt, indem Ihr DNA mit Referenzpopulationen aus verschiedenen Weltregionen verglichen wird. Die Komponenten des Modells stehen für diese Referenzen und hängen von den zugrunde liegenden Daten und Annahmen ab.
Dieser Rechner nutzt 4 sorgfältig ausgewählte modern Populationen als Referenzen und ermöglicht eine detaillierte Darstellung Ihrer genetischen Ähnlichkeit.
So funktioniert es
- Ihr DNA wird mit 4 Referenzpopulationen verglichen
- Modern-Populationen dienen als genetische Referenzen
- Die Ergebnisse zeigen Ihre genetische Ähnlichkeit zu diesen Populationen
- Ein vielfältiges Referenzpanel verbessert die Schätzungen
Ihre Ergebnisse verstehen
Ihre Ergebnisse zeigen Prozentsätze der genetischen Ähnlichkeit zu diesen Referenzpopulationen. Beachten Sie diese Punkte:
- Die Ergebnisse spiegeln genetische Ähnlichkeit wider, nicht nachgewiesene direkte Abstammung
- Modern-Populationen werden als Referenzen verwendet
- Die Prozentsätze geben relative Beiträge im Modell an
- Die Ergebnisse sind Schätzungen auf Basis der verfügbaren Referenzdaten
