Dodecad Globe 4

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
