MDLP K12b Supervised
MDLP K12b Supervised estimates ancestry across 12 curated components (African_HG, Amerindian, ANI, ASI, NEA, SEA, Arctic, Caucasian, Northeuropean, Volga_Ural, Papuan, Siberian). Suitable for global users—researchers, genealogists, and enthusiasts—it provides interpretable proportions tied to historical and migratory patterns, offering a clear, comparative view of deep and recent admixture while noting model-dependent limits.

À propos de ce calculateur
The MDLP K12b Supervised calculator quantifies an individual's genetic ancestry across twelve curated reference components, using a supervised modeling approach that ties modern and ancient population signals to interpretable labels. It analyzes genotype data to estimate proportions from African_HG (Hunter-Gatherer), Amerindian, ANI (Ancestral North Indian), ASI (Ancestral South Indian), NEA (Northeast Asian), SEA (Southeast Asian), Arctic, Caucasian, Northeuropean, Volga_Ural, Papuan, and Siberian sources. Designed for worldwide users—researchers, genealogists, informed consumers, and enthusiasts—this tool translates complex multilocus patterns into clear component scores and regional affinities.
Users gain insight into deep and recent admixture: the calculator highlights contributions that reflect prehistoric expansions (for example, Neolithic farmer vs. hunter-gatherer legacies), historic migrations across Eurasia and the Americas, and localized features such as South Asian ANI/ASI structure or Arctic and Siberian inputs. The supervised framework provides stability and interpretability by anchoring estimates to explicit reference populations, making cross-sample comparisons straightforward. Results can suggest likely macro-regional ancestry, detect minority or unexpected contributions, and guide further investigation with more specialized methods.
Contextually, MDLP K12b bridges modern population genetics and ancient signatures: components represent clusters that are meaningful in anthropological and historical terms while remaining practical for personal and population-level interpretation. The calculator is valuable because it balances interpretability with resolution, offering comparable output across diverse global samples. Users should note that component labels are model-dependent and depend on the chosen references; estimates are best interpreted as relative affinities rather than absolute “pure” ancestries. When combined with geographic, historical, and
Populations de référence
Les populations utilisées comme références génétiques dans ce calculateur
12 populations de référence
African
- African_HG (Hunter-Gatherer): Designates ancient African ancestry specifically from hunter-gatherer populations. These groups often exhibit genetic diversity distinct from more recent African lineages.
American
- Amerindian: Ancestry associated with the indigenous peoples of the Americas.
Asian
- ANI (Ancestral North Indian): A component of South Asian genetic ancestry, distinct from ASI (Ancestral South Indian).
- ASI (Ancestral South Indian): A component of South Asian genetic ancestry, separate from ANI (Ancestral North Indian).
- NEA (Northeast Asian): Genetic ancestry encompassing populations of Northeast Asia, including China, Korea, Japan, and parts of Siberia.
- SEA (Southeast Asian): Genetic ancestry from the Southeast Asian region, including countries like Vietnam, Thailand, the Philippines, and Indonesia.
Arctic
- Arctic: Refers to the genetic ancestry of indigenous populations inhabiting the far northern regions of the world, such as the Inuit and related groups.
European
- Caucasian: Genetic ancestry associated with populations of the Caucasus region (between the Black Sea and Caspian Sea). It's important to note this term can be problematic, as it links to outdated racial classifications.
- Northeuropean: Genetic ancestry associated with Northern European populations, encompassing regions like Scandinavia and the British Isles.
- Volga_Ural: Genetic ancestry related to populations around the Volga River and Ural Mountains in Russia, often with mixed European and Finno-Ugric heritage.
Oceanian
- Papuan: Genetic ancestry found in populations native to Papua New Guinea and neighboring areas of Melanesia.
Siberian
- Siberian: Genetic ancestry associated with the indigenous populations of Siberia (a vast region within Russia).
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 modernes et 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 Moderne et 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 Moderne et 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
