Dodecad K7b
Dodecad K7b — Global 7-component admixture
A concise, modern admixture calculator that breaks a genome into seven broad ancestral components using worldwide reference populations (South Asian, West Asian, Siberian, African, Southern, Atlantic_Baltic, East Asian, Asian, African, European). Ideal for genealogists, students, and researchers seeking a rapid, interpretable global ancestry snapshot and a starting point for deeper analyses.

Dodecad K7b — Modern global admixture calculator
The Dodecad K7b calculator decomposes a DNA sample into seven broad ancestral components using a curated set of modern reference populations from across the world. It provides a clear, interpretable overview of major continental and subcontinental ancestry in a contemporary framework, suitable for global comparisons and initial hypothesis generation.
What this calculator analyzes
- Genome-wide SNP genotype data summarized into seven ancestry components using model-based clustering (ADMIXTURE-style inference).
- Affinities to the provided reference groups: South Asian, West Asian, Siberian, African, Southern, Atlantic_Baltic, East Asian, Asian, African, European.
- Relative signals of recent admixture versus deeper shared ancestry across global populations.
Who it's designed for
- Genealogists and ancestry enthusiasts wanting a straightforward global ancestry snapshot.
- Students and researchers exploring broad-scale population structure and comparative patterns.
- Anyone curious how their genome aligns with major modern population clusters.
Insights you can gain
- Percentage breakdown across broad ancestral clusters that reflect major geographic ancestries.
- Which reference groups your genome most closely resembles and where mixture signals are strongest.
- A baseline for interpreting migration history and contact events suggested by your admixture profile.
Historical and genetic context Human genetic variation is shaped by millennia of migration, isolation, and admixture. K7b captures broad components that often correlate with large geographic and historical groups (e.g., South Asian, West Asian, East Asian, African, European). These components are statistical constructs: informative for comparison but not precise proxies for cultural or ethnic identity. Note that similar labels (e.g., two "African" entries) can reflect distinct reference clusters or sampling sets.

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 7 sorgfältig ausgewählte modern Populationen als Referenzen und ermöglicht eine detaillierte Darstellung Ihrer genetischen Ähnlichkeit.
So funktioniert es
- Ihr DNA wird mit 7 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
