Admixture Calculator

MDLP K12b

MDLP K12b is a global admixture calculator (ModernAncient era) that estimates ancestry across 12 reference components—ANI, ASI, Northeuropean, Caucasian, Volga Ural, African HG, NEA, Siberian, Arctic, SEA, Papuan, and Amerindian. It’s designed for researchers, genealogists, and ancestry enthusiasts seeking a nuanced view of regional and deep ancestral affinities worldwide. Results offer probabilistic, comparative insights into migration and population history.

About This Calculator

MDLP K12b is a global admixture calculator designed to estimate the proportional ancestry of an individual across twelve informative population components. It blends modern and deep-time reference signals (ModernAncient era) to reveal both recent regional ancestry and older population structure. The model reports contributions from: ANI (Ancestral North Indian), ASI (Ancestral South Indian), Northeuropean, Caucasian, Volga Ural, African HG (Hunter‑Gatherer), NEA (Northeast Asian), Siberian, Arctic, SEA (Southeast Asian), Papuan, and Amerindian. Who it’s for: the calculator suits researchers, genealogists, informed hobbyists, and anyone curious about global genetic roots. Because it uses worldwide reference populations, it is particularly useful for people with complex or mixed heritage, including those with South Asian, Eurasian, Indigenous American, Siberian, Oceanian, or African lineages. What it analyzes and the insights you can gain: MDLP K12b assesses genome-wide allele frequencies and assigns proportions to each reference cluster. Results help you understand continental and subcontinental ancestry patterns (for example, the ANI/ASI cline characteristic of South Asia), detect Northeuropean vs. Caucasian/Volga-Ural influences in Eurasia, and identify northern Asian signatures (NEA, Siberian, Arctic). Presence of SEA, Papuan, or Amerindian components highlights Southeast Asian, Oceanian, or Native American connections; African HG flags deep African hunter-gatherer affinities. Context and limitations: The model simplifies continuous genetic variation into discrete components — a useful shorthand but not an exact genealogy. Proportions are probabilistic estimates dependent on the reference set and statistical method. Interpret results as a guide to ancestral affinities and migration history rather than definitive proofs of origin. Value proposition: MDLP K12b offers a balanced, interpretable snapshot of global ancestry with attention to both regional nuance (AN

Reference Populations

The populations used as genetic references in this calculator

12 Reference Populations

South Asian Continent

ANI (Ancestral North Indian): A distinct ancestral component found within modern South Asian populations.
ASI (Ancestral South Indian): A specific ancestral component distinct from Ancestral North Indian (ANI) within modern South Asian populations.

European Continent

Northeuropean: Genetic ancestry linked to populations of Scandinavia, the Baltic states, and neighboring regions.
Caucasian: Genetic heritage associated with populations originating from the Caucasus Mountains region, known for its ethnic and linguistic diversity.
Volga Ural: Ancestry found in populations around Russia's Volga River and Ural Mountains, exhibiting a mixture of European and Finno-Ugric influences.

African Continent

African HG (Hunter-Gatherer): Ancient African lineages stemming from populations with traditional hunter-gatherer lifestyles.

Asian Continent

NEA (Northeast Asian): Ancestry prevalent in populations of China, Korea, Japan, and parts of Siberia.
Siberian: Genetic ancestry found in the indigenous communities inhabiting the vast Siberian region of Russia.
Arctic: Ancestry linked to indigenous peoples who have adapted to the extreme climates of the far northern latitudes.
SEA (Southeast Asian): Genetic ancestry originating from the diverse populations of countries like Vietnam, Thailand, and Indonesia.

Oceanian Continent

Papuan: Describes the genetic heritage of populations native to Papua New Guinea and neighboring Melanesian regions.

Americas

Amerindian: Indigenous ancestry spanning diverse populations throughout both North and South America.

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
