Global Ancestry K38 — Modern-era admixture calculator
What this calculator analyzes
This tool computes proportional ancestry components using a 38-cluster admixture model applied to modern global populations. It compares your genotype to curated reference groups to estimate the proportion of heritage derived from continental, regional and subregional sources.
Who it's designed for
- Genetic genealogists, adoptees, and curious consumers seeking detailed ancestry breakdowns
- Population geneticists and students who want a compact, interpretable modern-era model
- Anyone interested in broad migration signals rather than fine-scale community-specific signatures
Insights you can gain
- Percentage breakdown of ancestry across Europe, Asia, Africa, the Americas, and Oceania
- Detection of multi-regional admixture (e.g., Eurasian + African + Native American contributions)
- Relative affinities to fine-grained references such as Scandinavian, West African, Mongol, Polynesian, and Mesoamerican clusters
- Context for recent migrations and mixture events reflected in your genome
Historical and genetic context
K-models partition genetic variation into interpretable components that reflect shared ancestry and historical migrations. This modern-era K38 emphasizes present-day population structure—useful for reconstructing recent admixture and continental-level ancestry—while intentionally excluding separate Jewish clusters to avoid overfitting to those community-specific signatures.
Why this calculator is valuable
- Broad, globally representative reference set (35 major groups) for robust, comparative results
- Balanced resolution: detailed enough to be informative, simple enough to avoid misleading micro-assignations
- Clear presentation of admixture proportions to inform genealogical hypotheses and research leads

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 38 populations modernes soigneusement sélectionnées comme références, pour une répartition détaillée de votre similarité génétique.
Comment ça fonctionne
- Votre ADN est comparé à 38 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
