MDLP K12d
MDLP K12d is an ancient-era admixture calculator that estimates 12 deep ancestral components (Arctic, African, WHG, Siberian, EHG, SEA, CHG, SHG, Papuan, Natufian, Neolithic, ASI). Designed for global samples, it highlights prehistoric genetic contributions tied to hunter-gatherers, Neolithic farmers, and regional ancient populations—useful for enthusiasts, students, and researchers exploring deep ancestry.

À propos de ce calculateur
MDLP K12d is an ancient-era admixture calculator that decomposes a DNA sample into 12 deep-time ancestral components derived from widely distributed reference groups. It estimates proportions of Arctic, African, Western Hunter-Gatherer (WHG), Siberian, Eastern Hunter-Gatherer (EHG), Southeast Asian (SEA), Caucasus Hunter-Gatherer (CHG), Southern Hunter-Gatherer (SHG), Papuan, Natufian, Neolithic, and Ancestral South Indian (ASI) ancestry. The model is designed for world-wide samples and is useful to anyone interested in understanding the deep, prehistoric layers of genetic heritage: hobbyist genealogists, population geneticists, students, and anyone curious how ancient migrations contributed to today’s genomes.
What this calculator analyzes: MDLP K12d compares an individual’s genetic markers to reference clusters that approximate ancient populations and returns a proportional breakdown. These components act as lenses on major prehistoric events — for example, the spread of Neolithic farming, movements of Eurasian hunter-gatherers, Steppe-related influences captured by EHG/CHG contrasts, and deep southern and Papuan/Southeast Asian signals in Asia and Oceania.
Insights users can gain: quantitative estimates of ancestral contributions linked to archaeological and population histories; patterns that suggest regional affinities, ancient admixture events, or continuity with specific prehistoric groups; and a framework to compare samples across regions or time. The calculator contextualizes results with a genetic narrative: Out-of-Africa dispersals, hunter-gatherer structure across Europe and Siberia, Neolithic farmer expansions, south and southeast Asian deep ancestry (ASI/SEA/Papuan), and Levantine/Natufian influences.
Why it’s valuable: MDLP K12d condenses complex population history into an accessible set of components that are informative for hypothesis generation, teaching, and comparative analyses. Caveats: component labels are simplified shorthand, estimates are
Populations de référence
Les populations utilisées comme références génétiques dans ce calculateur
12 populations de référence
Arctic
- Indigenous peoples inhabiting the Arctic regions of the world, adapted to the cold climate and traditionally rely on hunting, fishing, and reindeer herding.
African
- Diverse group of populations native to the African continent, with a wide range of ethnic groups, languages, and cultures.
Western Hunter-Gatherer (WHG)
- Hunter-gatherer populations that inhabited Western Europe before the arrival of farmers from the Near East.
Siberian
- Indigenous peoples inhabiting Siberia, a vast region in northern Asia, with diverse ethnic groups traditionally practicing nomadic pastoralism and reindeer herding.
Eastern Hunter-Gatherer (EHG)
- Hunter-gatherer populations that inhabited Eastern Europe before the arrival of farmers from the Near East.
Southeast Asian (SEA)
- Diverse group of populations inhabiting Southeast Asia, a region of great cultural and linguistic diversity.
Caucasus Hunter-Gatherer (CHG)
- Hunter-gatherer populations that inhabited the Caucasus region before the arrival of farmers from the Near East.
Southern Hunter-Gatherer (SHG)
- Hunter-gatherer populations that inhabited Southern Europe before the arrival of farmers from the Near East.
Papuan
- Indigenous peoples inhabiting the island of New Guinea and surrounding islands, genetically distinct from other populations in Southeast Asia and Oceania.
Natufian
- Late Epipaleolithic culture in the Levant region of the Near East, semi-sedentary hunter-gatherers who lived in villages and practiced early forms of agriculture.
Neolithic
- Period of human history characterized by the transition from a hunter-gatherer lifestyle to a settled agricultural lifestyle.
Ancestral South Indian (ASI)
- Ancient population that contributed to the ancestry of modern South Asians, genetically distinct from the Ancient North Indians (ANI).
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 12 populations antiques soigneusement sélectionnées comme références, pour une répartition détaillée de votre similarité génétique.
Comment ça fonctionne
- Votre ADN est comparé à 12 populations de référence
- Des populations Antique 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 Antique 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
