Global Ancestry K45
Global Ancestry K45 maps your genome to a high‑resolution panel of 33 reference populations to reveal fine regional ancestry across Africa, Europe, Asia, Oceania and the Americas. Ideal for genealogists, researchers and curious users, it highlights subtle subcontinental signals (e.g. Anatolia, Persia, Finno‑Ugric, South Indian, Papuan) and frames personal DNA within human migration history.

Global Ancestry K45 — what it analyzes
This calculator decomposes an individual's genome into up to 45 modeled components using a curated panel of 33 modern and regionally informative reference populations. It measures proportions of shared genetic ancestry across Africa, Europe, West and Central Asia, South and East Asia, Oceania and the Americas to reveal fine-grained regional signals rather than broad continental labels.
Who it's designed for
- Genetic genealogy enthusiasts and adoptees seeking more precise regional clues
- Researchers and students comparing population structure or admixture patterns
- Anyone curious about how recent and ancient migrations shaped their DNA
What insights you can gain
- Percentage breakdowns of ancestry linked to specific regions (e.g. West Africa, Anatolia/Caucasus, Baltic, Persia/Mesopotamia, Southern Indian Subcontinent, Papuan)
- Detection of minor components that signal historical contacts (e.g. Siberian, Finno‑Ugric, North Amerindian)
- A nuanced view of European substructure (Basque, Sardinian, North Italy, Iberian, Scandinavian, England)
Historical and genetic context
Modern human genomes are mosaics of lineages shaped by repeated migrations, isolations and admixture events — Out‑of‑Africa dispersals, the spread of agriculture, steppe migrations, maritime contacts and prehistoric colonizations of Oceania and the Americas. K45 uses contemporary reference panels to map these echoes onto individual genomes, helping to place personal ancestry into that global story.
Why this calculator is valuable
- High resolution across underrepresented regions (e.g. North East Africa, Tibeto‑Burmese, South Central Asia)
- Balanced set of 33 references for both large continental groups and fine regional subgroups
- Actionable clues for follow‑up genealogical research without overclaiming precision

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 45 cuidadosamente seleccionadas modern populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
- Tu DNA se compara con 45 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
