Global Ancestry K42

Modern World K42 is a curated global admixture calculator that compares your DNA to 42 reference populations. It provides modern-era ancestry proportions across Africa, Europe, Asia, Oceania and the Americas, revealing migration signals (Bantu, Indo-European, Austronesian, Silk Road, colonial-era admixture) and offering fine-grained regional insights for genealogists, adoptees and researchers. Probabilistic—interpret alongside other evidence.

À propos de ce calculateur

Modern World K42 is a curated admixture calculator that estimates the modern ancestral composition of a DNA sample by comparing it to 42 carefully chosen reference populations from around the globe. Designed for genealogists, adoptees, ancestry enthusiasts, students and population researchers, this tool transforms genotype data into clear proportional affinities across major regions — Africa, Europe, the Middle East, South and Central Asia, East and Southeast Asia, Oceania and the Americas — with fine-grained subregional resolution.

What it analyzes: Modern World K42 quantifies how much your DNA resembles each reference population (for example: Northern Africa, Balochistan, Anatolia and the Caucasus, Southeast Asia Austronesian, Melanesia, Native American Andean, and many European subgroups). The calculator highlights mixture signals that reflect recent and ancient migrations, such as Bantu expansions, North African and Near Eastern exchanges, Neolithic farmer and Indo-European impacts in Europe, Silk Road and Central Asian gene flow, Austronesian dispersals across Island Southeast Asia and the Pacific, and colonial-era admixture in the Americas.

What you can learn: proportional ancestry estimates, primary regional affinities, and subtle secondary signals that suggest historical contacts or recent admixture. Results are useful for constructing hypotheses about family origins, guiding further genealogical research, or informing more detailed population studies.

Why it’s valuable: The 42 reference populations are curated to balance geographic breadth and resolution, focusing on modern-era signatures that are relevant to contemporary genealogical questions. The interface emphasizes transparent, interpretable outputs and encourages responsible use: admixture estimates are probabilistic, depend on reference composition, and do not identify individuals’ specific ancestors. For best interpretation, combine admixture results with documentary genealogy, uniparental marker

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 42 populations modernes soigneusement sélectionnées comme références, pour une répartition détaillée de votre similarité génétique.

Comment ça fonctionne

  • Votre ADN est comparé à 42 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
