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.

Comprendre l'analyse d'admixture
Découvrez le fonctionnement des calculateurs d'admixture et comment interpréter vos résultats
Qu'est-ce que l'analyse d'admixture ?
L'analyse d'admixture est une méthode qui permet d'estimer votre similarité génétique en comparant votre ADN à des populations de référence du monde entier. On peut la voir comme une composition de votre profil génétique, où les composantes représentent différentes populations de référence.
Ce calculateur utilise 28 populations modernes soigneusement sélectionnées comme références, pour une répartition détaillée de votre similarité génétique.
Comment ça fonctionne
- Votre ADN est comparé à 28 populations de référence
- Des populations Moderne sont utilisées comme références génétiques
- Les résultats indiquent votre similarité génétique avec ces populations
- Un panel de référence diversifié améliore la précision des estimations
Comprendre vos résultats
Vos résultats affichent des pourcentages de similarité génétique avec ces populations de référence. Gardez à l'esprit les points suivants :
- Les résultats reflètent une similarité génétique, pas une ascendance directe démontrée
- Des populations Moderne sont utilisées comme références
- Les pourcentages indiquent une contribution génétique relative dans le modèle
- Les résultats sont des estimations fondées sur les données de référence disponibles
