Dodecad K12b — Modern 12-way Admixture Calculator
Dodecad K12b is a modern, global admixture calculator that decomposes an individual's genome into twelve ancestral components derived from broad reference populations. It analyzes allele frequency patterns across the genome to estimate proportional ancestry from: Gedrosia, Siberian, Northwest African, Southeast Asian, Atlantic Mediterranean, North European, South Asian, East African, Southwest Asian, East Asian, Caucasus, and Sub-Saharan groups.
Who it's for
- Genetic enthusiasts, genealogists, and curious individuals seeking a clear, comparative view of their deep ancestry
- Researchers and students who need a convenient, standardized 12-component breakdown for population comparisons
What you gain
- A breakdown of ancestry proportions that highlights major continental and regional contributions
- Contextual interpretation: which components typically reflect West Eurasian, African, South Asian, and East Asian heritage
- A starting point for historical inference—migration signals, admixture events, and regional affinities—when combined with archaeological and linguistic evidence
Genetic and historical context
K12b is an allele-frequency based model optimized for modern populations: it captures long-term regional differentiation rather than single recent genealogical events. Components like Gedrosia and Caucasus reflect shared West Asian ancestries, while Atlantic Med and North European resolve diverse European contributions. Asian and African diversity are represented through East Asian, Southeast Asian, Siberian, East African, and Sub-Saharan components.
Why use Dodecad K12b
- Balanced resolution: twelve components provide interpretable regional signals without overfitting
- Global scope: designed for worldwide application, useful for multi-ethnic samples
- Comparative utility: easy to compare individuals, populations, and published datasets
Limitations
This is a statist

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 12 sorgfältig ausgewählte modern Populationen als Referenzen und ermöglicht eine detaillierte Darstellung Ihrer genetischen Ähnlichkeit.
So funktioniert es
- Ihr DNA wird mit 12 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
