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
Populações de referência
As populações utilizadas como referências genéticas nesta calculadora
4 Poblaciones de referencia
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.
Como interpretar a análise de mistura genética
Descubra como funcionam as calculadoras de mistura genética e como interpretar os resultados
O que é a análise de mistura genética?
A análise de mistura genética estima a semelhança genética comparando o seu DNA com populações de referência de diferentes partes do mundo. Os componentes do modelo representam essas referências e dependem dos dados e pressupostos utilizados.
Esta calculadora utiliza 4 cuidadosamente seleccionadas modern populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
- Tu DNA se compara con 4 poblaciones de referencia
- Modern se utilizan como referencias genéticas
- Os resultados mostram a sua semelhança genética com estas populações
- A diversidade do painel de referência influencia as estimativas
Como interpretar seus resultados
Os resultados mostram percentagens de similaridade genética com estas populações de referência. Tenha presente estes pontos:
- Os resultados reflectem a semelhança genética, não ascendência directa demonstrada
- Modern se utilizan como referencias
- As percentagens indicam contribuições relativas no modelo
- Os resultados são estimativas baseadas nos dados de referência disponíveis
