Admixture Calculator

MDLP K18a

MDLP K18a is a global admixture calculator that estimates ancestry proportions across 18 reference components. Suitable for genealogists, researchers, and curious users, it reveals continental and regional genetic signals — from African hunter-gatherer and North African to Indian, Siberian, Sardinian, and Oceanian influences — offering a nuanced, historically informed view of your genetic makeup.

About This Calculator

MDLP K18a is a modern admixture calculator that decomposes an individual’s genome into 18 biologically and geographically informed components. Designed for a global audience — genealogists, population geneticists, students, and curious individuals — it evaluates ancestry proportions using reference signals that span Africa, Europe, Asia, the Near East, and Oceania. Reference groups include African HG, ANI, Basque, Caucasian, East Asian (EA), East Africa, East Europe, Indian, Near East, North Africa, Oceanian, Sardinian, Siberian, South Europe, Subsaharian, Turkic, Volga-Ural, and West Europe. What it analyzes: MDLP K18a estimates relative contributions from distinct ancestral clusters, highlighting both deep, ancient lineages and more recent regional admixture. It uses allele frequency patterns to infer proportions that reflect historical migrations, isolation, and gene flow between populations. Who it’s for: This calculator is intended for users worldwide seeking a balanced, interpretable picture of genetic ancestry. It suits hobbyists exploring family origins, researchers comparing population structure, and educators illustrating how modern genomes are mosaics of past encounters. Insights you can gain: Results reveal primary continental ancestries and finer regional signals (for example, differentiation between Sardinian, Basque, South and West European components), detect South Asian-related (ANI/Indian) inputs, and identify contributions from North and East African, Siberian, or Oceanian lineages. These proportions can illuminate migration histories, admixture events, and relative genetic affinity to reference groups. Context and value: By integrating geographically diverse references, MDLP K18a bridges older, deep ancestry signals and modern population structure. It helps contextualize personal results within broader human history — such as expansions from the Near East, Eurasian steppe movements, African diversity, and Austronesian/Oceanian dispersals — wh

Reference Populations

The populations used as genetic references in this calculator

18 Reference Populations

African HG: Hunter-gatherer populations in Africa.
ANI: Ancestral North Indian, related to ancient Indo-European speakers.
Basque: Population native to the Basque Country, between Spain and France.
Caucasian: Refers to populations from the Caucasus region.
EA (East Asian): Populations from East Asia.
East Africa: Populations from the eastern region of Africa.
East Europe: Populations from the eastern part of Europe.
Indian: Populations from the Indian subcontinent.
Near East: Populations from the region, including parts of Western Asia and Eastern Mediterranean.
North Africa: Populations from the northern part of Africa.
Oceanian: Populations from the Pacific Islands and surrounding areas.
Sardinian: Population from the Italian island of Sardinia.
Siberian: Populations from Siberia, Russia.
South Europe: Populations from the southern regions of Europe.
Subsaharian: Refers to populations living south of the Sahara Desert.
Turkic: Populations speaking Turkic languages, mostly in Central Asia.
Volga Ural: Populations from the region near Volga River and Ural Mountains.
West Europe: Populations from the western part of Europe.

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 18 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 18 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
