Description
Mephisto K15 is a modern, global genetic admixture calculator that decomposes an individual's genome into 15 reference components to reveal ancestral affinities across the world. Built for hobby genealogists, academic researchers, clinicians exploring population structure, and curious individuals of any background, Mephisto K15 provides a clear, comparative snapshot of where ancestry signals concentrate and how different geographic and ethno-linguistic layers contribute to a genome. The calculator compares your genotype against fifteen reference populations — Mediterranean, Mozabite, Arabia, W_Africa, Omotic, Arctic, E_Asia, Khomani, Europe, Papuan, S_Asia, Caucasus, Siberia, E_Africa, and SE_Asia — returning proportional estimates that reflect deep and recent admixture. Users gain insights into continental-level ancestry, regional affinities (for example Mediterranean vs. Caucasus contributions), and signatures of historically documented migrations such as Eurasian expansions, African dispersals, or Austronesian and Papuan links in Oceania. Mephisto K15 is especially useful for people with mixed, understudied, or transcontinental heritage who want a nuanced portrait beyond broad continental labels. Beyond percentages, the calculator situates results within genetic and historical context: which components tend to co-occur, which reflect coastal vs. inland ancestries, and how certain components represent ancient hunter-gatherer, pastoralist, or agricultural expansions in simplified form. Results are model-based and best interpreted as hypotheses about ancestry rather than definitive lineage proofs. Mephisto K15 thus serves as an accessible teaching and exploration tool that bridges personal ancestry, population genetics, and historical demography, helping users ask better questions and pursue deeper study with appropriate caution and scientific curiosity.

Reference Populations

  • Mediterranean: A diverse region known historically for the interconnected cultures and civilizations around the Mediterranean Sea.

  • Mozabite: Indigenous Berber-speaking people primarily from the M'zab region in Algeria.

  • Arabia: Refers to populations originating from the Arabian Peninsula, with a rich history of trade and cultural exchange.

  • W_Africa (West Africa): Includes diverse ethnic groups in countries such as Nigeria, Ghana, and Senegal, known for rich cultural traditions and languages.

  • Omotic: Refers to ethnic groups from southwestern Ethiopia, speaking Omotic languages.

  • Arctic: Indigenous peoples of the Arctic regions, such as the Inuit, known for their adaptation to cold environments.

  • E_Asia (East Asia): Includes nations like China, Japan, and Korea, characterized by a long history of shared cultural and technological advancements.

  • Khomani: Indigenous San peoples primarily located in Southern Africa with ancient roots and unique cultural heritage.

  • Europe: Populations from the continent known for its diverse ethnic groups, languages, and cultural heritage.

  • Papuan: Indigenous groups from the island of New Guinea, known for their diverse languages and cultures.

  • S_Asia (South Asia): Encompasses countries like India, Pakistan, and Bangladesh, with a rich history of religions and cultural practices.

  • Caucasus: Region between Europe and Asia, home to a variety of ethnic groups with complex historical ties.

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

How It Works

Key Points
  • Your DNA is compared to 15 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
  • Modern populations are used as references
  • Percentages indicate relative genetic contribution from each population
  • Results are estimates based on available reference data
