Description
MDLP K18b is an ancestry admixture calculator that estimates proportional ancestry using a 17-component reference panel tuned to ancient and deep population structure. Designed for global users — hobbyists, genealogists, population geneticists, and anyone curious about biogeographic roots — it translates your genetic data into percentages that reflect affinities to components such as ANI (Ancestral North Indian), ASI (Ancestral South Indian), CHG (Caucasus Hunter‑Gatherer), Northeuropean, SouthEuropean, NearEast, various East and Southeast Asian groups (EA, NorthEastAsian, SEA), Siberian, Uralic, Arctic, Amerindian, Melanesian, Papuan, Paleoafrican and Subsaharian ancestries. What it analyzes: MDLP K18b compares your genotype to modeled ancestral clusters representing deep and regionally distinct lineages. The calculator quantifies mixtures of ancient and modern-informative components to reveal likely population affinities and broad migratory signals rather than pinpoint recent family-level relationships. Insights you can gain: results show the proportional contribution of each component to your genome, highlighting major regional ancestries and smaller, legacy signals (for example CHG-related Caucasus influence, ANI/ASI structure in South Asia, or Papuan/Melanesian signatures in Oceania). Users can use these outputs to explore hypotheses about migration, admixture events, and continental ancestry composition across time. Historical/genetic context: MDLP K18b bridges modern genomes with ancient-informed clusters. Components like CHG, ANI, and ASI reflect deep prehistoric population structure revealed by ancient DNA studies; Paleoafrican and Subsaharian categories acknowledge Africa’s deep diversity. The inclusion of Arctic, Siberian and Uralic components captures northern Eurasian dynamics. Why it’s valuable: the calculator offers broad, interpretable ancestry decomposition with global coverage. It’s a practical tool for comparative exploration, educational use,

Reference Populations

  • Amerindian: Indigenous peoples of the Americas with diverse cultures and languages.
  • ANI: Ancestral North Indian, contributing to South Asian ancestry.
  • Arctic: Populations in the Arctic region, including Inuit and other indigenous groups.
  • ASI: Ancestral South Indian, contributing to the Dravidian populations of South Asia.

Caucasus and Middle East

  • CHG: Caucasus Hunter-Gatherer, ancient populations from the Caucasus region.
  • NearEast: Populations from the Middle East with ancient ties to early civilizations.

Asia

  • EA (EastAsian): Diverse populations from East Asia, including Chinese, Japanese, and Koreans.
  • NorthEastAsian: Populations from northeastern Asia, including Siberia and Mongolia.
  • Siberian: Indigenous peoples from Siberia with distinct genetic backgrounds.

Europe

  • Northeuropean: Populations from Northern Europe, including Scandinavians and the British Isles.
  • SouthEuropean: Southern European populations, including Mediterranean groups.

Oceania

  • Melanesian: Indigenous peoples of Melanesia with distinct genetic makeup.
  • Papuan: Indigenous peoples of Papua New Guinea and surrounding islands.

Africa

  • Paleoafrican: Ancient African populations contributing to early human migrations.
  • Subsaharian: Populations from Sub-Saharan Africa with rich genetic diversity.

Southeast Asia

  • SEA (SoutheastAsian): Diverse populations from Southeast Asia, including Thai, Vietnamese, and Filipinos.

Eurasian Steppes

  • Uralic: Peoples from the Ural region, including Finnic and Hungarian groups.

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 ancient populations as references, allowing for a detailed breakdown of your genetic heritage.

How It Works

Key Points
  • Your DNA is compared to 18 reference populations
  • Modern populations are used as references
  • Results show your genetic similarity to these populations

Understanding Your Results

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

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