Dodecad Weac
Dodecad Weac — Four‑way global admixture in one view
A modern, easy‑to‑use autosomal admixture calculator that partitions genomes into Atlantic–Baltic, Near‑East, Far‑East, and Africa components. Designed for users worldwide, it delivers a clear, high‑level ancestry profile useful for genealogy, teaching, and initial population‑genetic exploration. Fast, interpretable, and a great starting point for deeper analyses.

Dodecad Weac — Modern four-way admixture calculator
Dodecad Weac is a compact, intuitive autosomal admixture calculator that models an individual's ancestry as proportions of four broad reference populations: Atlantic–Baltic, Near‑East, Far‑East, and Africa. Designed for modern samples from anywhere in the world, it summarizes genome-wide SNP variation into a clear, interpretable four‑component profile.
What this calculator analyzes
- Genome‑wide autosomal markers to estimate the proportion of ancestry traceable to each of the four reference axes.
- Population‑level allele frequency contrasts to resolve broad continental and subcontinental signals.
Who it's designed for
- Enthusiastic genealogists and family historians seeking big‑picture ancestry breakdowns.
- Researchers and students who want a simple, reproducible four‑way model for exploratory analyses.
- Curious individuals worldwide who want a concise summary of major continental contributions to their genome.
Insights you can gain
- Relative contributions from Atlantic–Baltic, Near‑Eastern, Far‑Eastern, and African source clusters.
- Broad historical signals such as Eurasian clines, signals of transcontinental admixture, and major migration legacies (e.g., movements across Eurasia, Near‑Eastern expansions, and African gene flow).
- A starting point for deeper analysis: results can guide targeted follow‑up with higher‑resolution regional panels or haplotype‑based methods.
Context and limitations
- The four‑component model is deliberately simple: it emphasizes clarity over fine regional detail. It captures major ancestry streams shaped by events like Out‑of‑Africa dispersals, Holocene farmer and pastoralist movements, and later regional contacts.
- Interpret results as approximations tied to the chosen reference sets; they are best combined with historical, archaeological, and regional genetic evidence.
Why this calculator is valuable
- Fast, accessible, and easy to interpret—idea
Referenzpopulationen
Die in diesem Rechner als genetische Referenzen verwendeten Populationen
4 Referenzpopulationen
Atlantic-Baltic
- Description: This region encompasses parts of Northern and Western Europe, including the British Isles, Scandinavia, and the areas around the Baltic Sea. The populations in this region are historically interconnected through maritime trade, shared cultural ties, and the exchange of genetic material over several millennia.
Near-East
- Description: Often considered the cradle of civilization, this region includes parts of the Eastern Mediterranean and extends into Western Asia. It has diverse populations with rich histories of ancient empires and significant contributions to early human civilization.
Far-East
- Description: This area refers to Eastern Asia, including countries like China, Japan, and Korea. Populations in this region have ancient roots, with distinct cultural, linguistic, and genetic lineages that have evolved over thousands of years.
Africa
- Description: The continent is characterized by a tremendous diversity of cultures and languages, with populations that date back to the origins of anatomically modern humans. Africa is divided into numerous ethnic groups, each with unique histories and genetic backgrounds.

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
