About This Calculator

**Tolan K18 M4 — Modern Global Admixture Calculator** This calculator analyzes an individual’s genome to estimate proportions of ancestry from 18 modern reference populations, providing a clear, interpretable breakdown of global genetic affinity. It compares your genotype to balanced regional panels spanning Atlantic, European, Mediterranean, Near Eastern, Steppe, Central and South Asian, East and Southeast Asian, African, and coastal Indian Ocean clusters. Who it’s for: - Genetic researchers and population geneticists exploring contemporary admixture patterns - Genealogists and DNA hobbyists seeking fine-grained, region-level ancestry estimates - Anyone worldwide curious about recent ancestral contributions in a modern context What you learn: - Proportional ancestry estimates across 18 reference groups (e.g., Atlantic, Central Euro, Steppe-Russia, East-Anatolia, Bay-of-Bengal, East-Asia, Equatorial Africa) - Regional affinity that highlights recent admixture events and broad migration-related signals - Contextual interpretation linking proportions to plausible historical movements (e.g., maritime trade, steppe migrations, Anatolian and Mediterranean exchanges) Why it matters: - Modern-era focus: reference panels and algorithm choices tuned for recent, global genetic structure rather than deep ancient components - Balanced set of 18 populations offers granularity across Europe, Asia, Africa, and adjoining seas, helping distinguish nearby regional sources - Actionable and clear outputs suitable for reports, family history projects, and comparative research Notes and limitations: - Results are probabilistic estimates based on reference samples; they summarize similarity to present-day populations, not direct proof of individual ancestors - Regional labels are simplifications of continuous genetic variation; interpret in conjunction with historical, archaeological, and genealogical evidence Tolan K18 M4 gives a practical, scientifically grounded window into your

Reference Populations

The populations used as genetic references in this calculator

18 Reference Populations

  • A-Atlantic: Populations living along the Atlantic coast, including parts of Western Europe and possibly extending to the North African coast.

  • B-Central-Euro: Populations found in the central regions of Europe, encompassing areas like Germany, Poland, and Austria.

  • C-North-Euro: Northern European populations, including countries such as Scandinavia and the Baltic states.

  • D-West-Med: Populations from the Western Mediterranean basin, including parts of Southern Europe and North Africa.

  • E-NW-Black_Sea: Populations located northwest of the Black Sea, potentially including regions in Eastern Europe.

  • F-East-Med: Populations around the Eastern Mediterranean, likely involving parts of the Near East and Southeastern Europe.

  • G-Steppe-Russia: Populations inhabiting the steppe regions of Russia, possibly including areas south of the Ural Mountains.

  • H-East-Caspian: Populations near the eastern shores of the Caspian Sea, covering parts of Central Asia.

  • I-East-Anatolia: Populations located in the eastern regions of Anatolia, which is present-day Turkey.

  • J-Persian-Gulf: Communities around the Persian Gulf, consisting of Arab Gulf states and regions in Southern Iran.

  • K-North-Russia: Populations residing in the northern expanses of Russia, often characterized by colder climates.

  • L-North-Africa&Near-East: Populations from North Africa extending to the Near East, including parts of Egypt, Libya, and the Levant.

  • M-Equatorial-Africa: Populations found around the equatorial regions of Africa, often characterized by tropical climates.

  • N-Central-Asia: Populations inhabiting the central parts of Asia, possibly including regions within Kazakhstan, Uzbekistan, and Turkmenistan.

  • O-South-Central-Asia: Populations in the southern and central areas of Asia, including countries like Afghanistan and northern India.

  • P-Bay-of-Bengal: Communities living around the Bay of Bengal, encompassing coastal regions of India, Bangladesh, and Myanmar.

  • Q-South-China-Sea: Populations on the coasts of the South China Sea, including countries such as Vietnam, the Philippines, and southern China.

  • R-East-Asia: Populations in East Asia, covering countries like China, Japan, and Korea.

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

How It Works

  • Your DNA is compared to 18 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
