À propos de ce calculateur
Global Ancestry K23 2017 is a high-resolution admixture calculator that estimates an individual’s genetic ancestry using a model of 23 ancestry components (K=23) derived from 161 curated reference populations worldwide. It compares your genotype to a broad panel spanning Europe, the Near East, North Africa, Sub‑Saharan Africa, South and Southeast Asia, East Asia, Siberia, the Americas and Oceania to report proportional affinities and regional signals.
Who this calculator is for:
- Researchers seeking a compact, replicable K=23 overview of global ancestry
- Genealogists and adoptees exploring multi‑regional roots
- Enthusiasts curious about fine‑scale continental and subcontinental ancestry
What this calculator analyzes:
- Genome‑wide allele frequency patterns matched to 23 modelled components
- Relative contributions from 161 modern reference populations (e.g., Western and Eastern Europe, Levant, Arabian Peninsula, North Africa, South Asia, East Asia, Siberia, Indigenous American groups, Oceania, and diverse African populations)
Insights you can gain:
- Percent‑level breakdowns of major ancestry components and regional affinities
- Signals of recent admixture versus older shared ancestry
- Clues to migratory and historical contacts (e.g., Eurasian steppe, Mediterranean, Trans‑Saharan interactions)
Context and limitations:
- K=23 is a modern, statistical model — components are abstractions that summarize genetic structure, not “pure” historical populations.
- Results depend on reference sampling, allele frequencies, and quality of input genotype data. Interpret as probabilistic affinities, not definitive identities.
Why this calculator is valuable:
- Combines broad geographic coverage (161 populations) with a compact, interpretable K=23 framework to reveal subtle multi‑regional patterns
- Useful as an exploratory tool alongside haplogroup and segment‑based analyses for building hypotheses about ancestry

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 23 populations modernes soigneusement sélectionnées comme références, pour une répartition détaillée de votre similarité génétique.
Comment ça fonctionne
- Votre ADN est comparé à 23 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
