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.

About This Calculator

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.

Reference Populations

The populations used as genetic references in this calculator

12 Reference Populations

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).

Understanding Admixture Analysis

Learn how admixture calculators work and how to interpret your results

What is Admixture Analysis?

Admixture analysis is a method used to estimate your genetic ancestry by comparing your DNA to reference populations from around the world. Think of it as creating a recipe of your genetic makeup, where the ingredients are different ancestral populations.

This calculator uses 12 carefully selected modern and ancient populations as references, allowing for a detailed breakdown of your genetic heritage.

How It Works

Your DNA is compared to 12 reference populations
Modern & Ancient populations are used as genetic references
Results show your genetic similarity to these populations
More accurate with a diverse reference panel

Understanding Your Results

Your results will show percentages of genetic similarity to these reference populations. Remember these important points:

Results reflect genetic similarity, not direct ancestry
Modern & Ancient populations are used as references
Percentages indicate relative genetic contribution
Results are estimates based on available reference data
