MDLP World 22

**MDLP World 22 — Global Modern+Ancient Admixture** A 22-component admixture model that blends modern and ancient reference proxies to reveal fine-scale global ancestry. Ideal for genealogists, researchers and curious users, it quantifies regional and prehistoric signals (Neolithic, Mesolithic, Siberian, Austronesian, Amerindian, African, Melanesian) to illuminate migration history and complex admixture patterns.

About This Calculator

**MDLP World 22 β€” Modern+Ancient Admixture Model** MDLP World 22 analyzes autosomal DNA using a 22-source reference panel that mixes modern and ancient proxies to reveal fine-scale global ancestry. The model quantifies how much of your genome matches diverse ancestral components such as **Atlantic Mediterranean Neolithic**, **North-European-Mesolithic**, **Indo-Iranian**, **Austronesian**, **Melanesian**, **Pygmy**, and multiple Amerindian, Siberian and African lineages. Who this is for: - Genetic genealogists and ancestry enthusiasts seeking detailed regional breakdowns - Researchers and students comparing modern/ancient signals - Anyone curious about migration histories and deep regional affinities What you learn: - Percent contributions from 22 reference populations spanning Eurasia, Africa, Oceania and the Americas - Signals of ancient demography (e.g., Neolithic farmer, Mesolithic hunter-gatherer, Paleo-Siberian and Austronesian inputs) - Modern admixture patterns from recent migrations and long-range contacts Historical and genetic context: The MDLP World 22 model combines modern population samples with proxies for ancient groups to provide a bridge between recent population structure and deeper prehistory. It highlights processes such as the spread of farming across the Mediterranean, Siberian and Beringian links to the Americas, Austronesian expansion into Island Southeast Asia and Oceania, and sub-Saharan and Pygmy diversity in Africa. Why it’s valuable: - High-resolution, globally focused panel with both modern and ancient components - Helps disentangle overlapping signals (e.g., distinguishing Atlantic Mediterranean Neolithic from North-European-Mesolithic) - Useful as a comparative tool alongside other calculators and archaeological records Caveats: Like all admixture models, results are model-dependent and approximate. Use MDLP World 22 as an informative lens β€” not a definitive pedigree β€” to explore your genetic ties to global human history.

Reference Populations

The populations used as genetic references in this calculator

22 Reference Populations

  • Pygmy: Indigenous populations primarily inhabiting the rainforests of Central Africa, known for their short stature.

  • West-Asian: Populations from the western part of Asia, which includes regions like the Middle East and the Caucasus.

  • North-European-Mesolithic: Ancient populations from Northern Europe during the Mesolithic period, between the Paleolithic and Neolithic ages.

  • Indo-Tibetan: People from the Himalayan region bridging India and Tibet, sharing cultural and genetic traits.

  • Mesoamerican: Indigenous cultures native to Mexico and Central America, including the Maya and Aztec civilizations.

  • Arctic-Amerind: Indigenous groups located in the Arctic regions of America, such as the Eskimos and Aleut.

  • South-America_Amerind: Indigenous populations from South America, including various groups like the Inca.

  • Indian: Refers to the diverse ethnic groups of India, with vast cultural, linguistic, and genetic diversity.

  • North-Siberian: Populations from the northern regions of Siberia, known for harsh climatic conditions.

  • Atlantic_Mediterranean_Neolithic: Populations from the Neolithic era around the Atlantic and Mediterranean regions, associated with early agriculture.

  • Samoedic: Indigenous peoples of Northern Siberia, including the Nenets and Enets.

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 22 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 22 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
