Global Ancestry K23 2013
Global Ancestry K23 (2013) — a 23‑component admixture model for worldwide users. It estimates regional ancestry proportions using 24 reference populations across Africa, Europe, Asia, Oceania and the Americas. Ideal for genealogy and population research, it offers fine-scale European and African substructure plus Asian, Near Eastern, Melanesian and Native American signals—interpretable proxies of historic gene flows.

Global Ancestry K23 (2013)
This calculator implements a 23-component global admixture model (K23) built from 24 curated reference populations spanning Africa, Europe, Asia, Oceania and the Americas. It analyzes a single autosomal genotype file to estimate the proportionate contribution of regional ancestries in an individual's genome, returning a compact, interpretable breakdown of genetic affinities.
Who it's for
- Researchers, genetic genealogy enthusiasts, and curious consumers seeking a higher-resolution, globally-aware admixture profile.
- People with mixed or uncertain ancestry who want to explore continental and subcontinental signals beyond coarse categories.
What it measures
- Proportional ancestry from modeled source groups such as North Africa, Benin–Togo, Nigeria, Senegal, Mali, Southeastern Bantu, Ivory Coast–Ghana, and Southcentral Hunter‑Gatherers for African structure.
- Detailed European components: West Europe, East Europe, Great Britain, Ireland, Iberian Peninsula, Italy–Greece, Scandinavia, Finland–NW Russia.
- West Asian and Caucasus signals: Near East, Caucasus.
- Asian and steppe-related contributions: Central Asia, South Asia, East Asia.
- Oceanian and Indigenous signals: Melanesia, Native American.
Historical and genetic context
- Each reference acts as a modern or proxy population representing historical gene flows (e.g., Bantu expansion, Eurasian farmer and steppe movements, trans‑Saharan and Atlantic coast West African variation, Austronesian/Oceanian and Native American ancestries).
- Results indicate affinities, not precise origins; components summarize genomes relative to the chosen reference panel and reflect both recent admixture and deeper shared ancestry.
Why it’s valuable
- High-resolution regional breakdown helps disentangle complex multi-continental backgrounds.
- Useful for comparative projects, population studies, and personal exploration when combined with careful interpretation.

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
