Admixture Calculator

MDLP K10a

MDLP K10a is a 10-component autosomal admixture calculator for global use. It estimates ancestry proportions from Indian, SEA, NEA, Papuan, Siberian, Caucasian, Westeurope, African, Amerindian, and Mediterranean reference groups. Designed for genealogists, researchers, and curious individuals, it gives a clear, interpretable snapshot of major continental and regional ancestry signals and their historical significance.

About This Calculator

MDLP K10a is a modern, 10-component autosomal admixture calculator designed to decompose an individual’s genome into proportions drawn from ten broad reference ancestries: Indian, Southeast Asian (SEA), Northeast Asian (NEA), Papuan, Siberian, Caucasian, Westeurope (Western European), African, Amerindian, and Mediterranean. It analyzes genome-wide SNP data to estimate the relative contribution of these regional ancestries to an individual’s recent and deep ancestry. The model is optimized for global use — suitable for individuals from any region who want a clear, comparative view of major continental and subcontinental ancestry components. Who it’s for: MDLP K10a is intended for genetic genealogy enthusiasts, population geneticists, clinicians wanting contextual ancestry information, and anyone curious about the large-scale ancestral makeup of themselves or their samples. It is useful for those exploring recent admixture (last few hundred to thousand years) and for researchers comparing broad population patterns across continents. What you’ll learn: The calculator provides quantitative ancestry proportions, highlighting mixtures such as South Asian vs. West Eurasian influence, East vs. Southeast Asian signals, Papuan and Australo-Melanesian contributions, African and Amerindian portions, and distinctions between Mediterranean and Western European components. These proportions can suggest historical processes — migrations, trade, colonization, and regional gene flow — such as the spread of Austronesian peoples, Eurasian steppe movements, African dispersals, or the peopling of the Americas. Context & value: MDLP K10a balances resolution and interpretability: ten well-differentiated clusters give meaningful geographic signal without overfitting. It complements haplogroup and local-ancestry analyses by providing a fast, interpretable snapshot of global ancestry composition. While powerful for broad interpretation, users should treat results as estimations that depend

Reference Populations

The populations used as genetic references in this calculator

10 Reference Populations

Indian: Represents the diverse ethnic groups of the Indian subcontinent, including Dravidian and Indo-Aryan populations.
SEA (Southeast Asian): Includes populations from countries like Thailand, Vietnam, and the Philippines, known for their Austroasiatic, Tai-Kadai, and Austronesian heritage.
NEA (Northeast Asian): Encompasses populations from China, Japan, Korea, and Mongolia, characterized by their Mongolic, Tungusic, and Sinic ancestry.
Papuan: Refers to the indigenous peoples of New Guinea and surrounding islands, known for their distinct Papuan languages.
Siberian: Involves the indigenous groups of Siberia, such as the Buryats and Yakuts, with Uralic and Altaic influences.
Caucasian: Encompasses populations from the Caucasus region, including Armenians, Georgians, and Chechens, with a rich blend of Indo-European and Caucasian languages.
Westeurope (Western European): Includes populations from Western Europe, primarily driven by Celtic, Germanic, and Romance ancestry.
African: Covers the vast ethnic diversity across Africa, from sub-Saharan groups like the Yoruba to North African Berbers.
Amerindian: Represents the indigenous peoples of the Americas, including tribes from North, Central, and South America, with diverse native languages.
Mediterranean: Involves populations from Southern Europe, North Africa, and the Near East with strong historical connections across the Mediterranean Sea.

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 10 carefully selected modern populations as references, allowing for a detailed breakdown of your genetic heritage.

How It Works

Your DNA is compared to 10 reference populations
Modern 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 populations are used as references
Percentages indicate relative genetic contribution
Results are estimates based on available reference data
