Global Ancestry K23 — Modern, worldwide admixture calculator
Global Ancestry K23 estimates the proportional ancestry of an individual using 23 modeled components derived from 22 geographically and historically informed reference populations. It is built to detect fine-grained regional signatures across Eurasia, Africa, the Americas, and Oceania in the context of modern human population structure.
What this calculator analyzes
- Genome-wide allele frequency patterns to infer percentage contributions from 22 reference clusters (Anatolian, Baltic, Central-Europe, East-Balkan, East-Med, Eastern-European, Finnish, North-West-European, South-Central-Europe, West-Balkan, West-Med, East-African, North-African, West-African, Central-Asian, East-Asian, South-Asian, South-East-Asian, South-Caucasus, West-Asian, Siberian-Central-Amerindian, South-Amerindian).
- Signals of recent and deep ancestry, distinguishing continental and sub-continental components.
Who it’s designed for
- Genealogy enthusiasts seeking regional breakdowns.
- Researchers and students exploring recent population structure and admixture.
- Individuals curious about how historical migrations shaped their genome across Eurasia, Africa, and the Americas.
Insights you can gain
- Percentage estimates of ancestral contributions from specific historical regions.
- Detection of mixed heritage (e.g., Eurasian–African–Amerindian admixture) and likely geographic sources.
- Clues to past migrations and contact events (Neolithic farmer expansions, Steppe ancestry pulses, Silk Road interactions, transatlantic movements).
Historical and genetic context
- Modern human populations reflect waves of migration, isolation and admixture: post-glacial recolonization, agricultural diffusion from Anatolia and the Near East, Bronze Age steppe movements, transcontinental trade and recent colonial-era gene flow. K23 frames individual genomes against these patterns using contemporary reference clusters.

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 23 cuidadosamente seleccionadas modern populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
- Tu DNA se compara con 23 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
