GedrosiaDNA World 25
GedrosiaDNA World 25 — Modern global admixture calculator
Compare your autosomal DNA to a 27-population modern reference panel and receive a clear, 25-component breakdown of global ancestry. Ideal for genealogy enthusiasts and researchers, it highlights regional affinities and historical migration signals (Steppe, EEF, Siberian, Oceanian, African, Native American, etc.) with accessible interpretation and caveats.

GedrosiaDNA World 25 — Modern global admixture calculator
GedrosiaDNA World 25 analyzes an individual's autosomal DNA against a modern reference panel to estimate ancestry proportions across the globe. Using 27 curated reference populations that span East and West Eurasia, Africa, Oceania, and the Americas, the calculator decomposes a genome into fine-grained components (World 25) to reveal regional affinities and historical admixture signals.
Who it’s for:
- Genetic genealogy enthusiasts who want context beyond continental labels
- Researchers seeking a compact, interpretable breakdown of global ancestry
- People curious about historical migrations reflected in their DNA
What you get:
- A percentage breakdown across 25 global components derived from 27 reference populations (e.g., East Asian, Siberian, Steppe, Early European Farmer, Near Eastern, South Asian, various African hunter-gatherer and Bantu-lineage references, Oceanian and Papuan, and multiple Native American clusters)
- Visual and numerical summaries highlighting dominant ancestries and minor signals
- Interpretive notes that connect components to known historical events (e.g., Neolithic farmer expansions, Steppe migrations, Austronesian dispersals, Native American founding waves)
Historical and genetic context: This calculator contextualizes modern genomes within major prehistoric and historic population movements. Components like EEF (Early European Farmers), W_STEPPE/E_STEPPE (Steppe ancestries), SHG/WHG hunter-gatherer signals, and multiple African and Oceanian references reflect lineages shaped by migrations, admixture, and founder effects over millennia.
Why it’s valuable:
- Global scope: meaningful resolution across all inhabited continents
- Balanced detail: enough components to highlight subtle mixtures without overwhelming jargon
- Modern reference panel: tuned to contemporary population structure for results relevant to living individuals
A note on interpretation: Results are statist

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 25 populations modernes soigneusement sélectionnées comme références, pour une répartition détaillée de votre similarité génétique.
Comment ça fonctionne
- Votre ADN est comparé à 25 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
