Global Ancestry K28 — Modern autosomal admixture at continental and regional resolution
This calculator analyzes your autosomal DNA and estimates the proportional ancestry you share with a curated set of modern reference populations. Using a high-resolution K28-style model tuned to 23 broad and regional groups, the tool places your genome on a continuum from continental-scale components (African, East Asian, European, Amerindian) down to regional clusters (Anatolian, Levantine, West Med, Horn of Africa, Siberian, Finnic, South Asian, etc.).
Who it’s for
- Genealogy enthusiasts and adoptees seeking detailed family origins
- Students and researchers comparing population structure in modern cohorts
- Anyone curious about how recent and ancient migrations shape personal ancestry
What insights you gain
- A proportional breakdown of ancestry across 23 modern reference groups
- Highlights of likely regional contributions (e.g., Anatolian farmer-related, Steppe-associated, West African, East African/ Horn signals)
- Context for unexpected components (historic trade routes, colonial-era admixture, long-distance migrations)
Historical and genetic context Human populations are the product of repeated migrations, isolates and mixtures: Out-of-Africa dispersals, Neolithic farming spread from Anatolia, Bronze Age steppe movements, Silk Road contacts, and more recent colonial and slave-trade-era exchanges. This calculator situates your DNA within that continuum using contemporary reference samples representing those geographic and historical legacies.
Why this calculator is valuable
- Balances broad continental categories with focused regional clusters for nuanced interpretation
- Designed for clarity: proportions are presented as interpretable components rather than deterministic labels
- Useful as a starting point for deeper research, genealogical triangulation, or curiosity-driven exploration
Notes: this is an ancestry inference tool, not a medical tes

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 27 cuidadosamente seleccionadas modern populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
- Tu DNA se compara con 27 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
