World and American Breakdown K28
World and American Breakdown K28 — A modern, fine-scale admixture calculator comparing your DNA to 28 globally and regionally informed reference populations. It emphasizes Indigenous American substructure while resolving European, African, Middle Eastern, Asian and Oceanian contributions. Ideal for genealogists, adoptees, and researchers seeking clearer historical and geographic ancestry insights.

World and American Breakdown K28 — Modern global admixture calculator
This calculator analyzes genome-wide patterns of genetic ancestry by comparing a tested genotype to a curated panel of 28 reference populations from across the globe, with dense representation of Indigenous American groups. It quantifies proportional ancestry from sources such as Cree, Raramuri, Pima, Zapoteco, Mixteco, Nahua, Maya, Quechua, Karitiana, Surui, multiple European clusters, African regions, Middle East, South and East Asia, Southeast Asia, Oceania and others to produce a refined breakdown relevant to modern populations.
Who it’s for
- Genealogy enthusiasts, adoptees, and family history researchers
- Population geneticists and students seeking comparative context
- Anyone curious about complex ancestry in the Americas and worldwide
What you’ll learn
- Estimated proportions from 28 reference groups, highlighting fine-scale Indigenous American structure and global contributions
- Signals of colonial-era admixture (European, African, and Middle Eastern inputs) and earlier migrations (Asian and Oceanian) where present
- Geographic and historical context to help interpret mixed ancestries
Why this matters
- Many global calculators aggregate Indigenous American ancestry into a single category; K28 resolves multiple autochthonous groups to reveal regional Indigenous substructure
- Useful for distinguishing nearby European clusters (Northern, Eastern, Southwest, Western) and African regional contributions
- Helps translate genetic estimates into historical narratives: migration corridors, colonization events, and recent admixture patterns
This tool prioritizes transparency: reference populations are named and geographically anchored, and results should be interpreted as statistical estimates rather than definitive labels. Use alongside family history, archival records, and regional knowledge for the most meaningful insights.

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 28 cuidadosamente seleccionadas modern populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
- Tu DNA se compara con 28 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
