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

Cómo interpretar el análisis de mezcla genética
Descubre cómo funcionan las calculadoras de mezcla genética y cómo interpretar los resultados
¿Qué es el análisis de mezcla genética?
El análisis de mezcla genética estima la similitud genética comparando tu ADN con poblaciones de referencia de distintas partes del mundo. Los componentes del modelo representan esas referencias y dependen de los datos y supuestos utilizados.
Esta calculadora utiliza 4 cuidadosamente seleccionadas modern poblaciones como referencias para describir con detalle la similitud genética.
Cómo funciona
- Tu ADN se compara con 4 poblaciones de referencia
- Modern se utilizan como referencias genéticas
- Los resultados muestran tu similitud genética con estas poblaciones
- La diversidad del panel de referencia influye en las estimaciones
Cómo interpretar tus resultados
Los resultados muestran porcentajes de similitud genética con estas poblaciones de referencia. Ten presentes estos puntos:
- Los resultados reflejan similitud genética, no ascendencia directa demostrada
- Modern se utilizan como referencias
- Los porcentajes indican contribuciones relativas en el modelo
- Los resultados son estimaciones basadas en los datos de referencia disponibles
