Global Ancestry K45

**Global Ancestry K45** maps your genome to a high‑resolution panel of 33 reference populations to reveal fine regional ancestry across Africa, Europe, Asia, Oceania and the Americas. Ideal for genealogists, researchers and curious users, it highlights subtle subcontinental signals (e.g. Anatolia, Persia, Finno‑Ugric, South Indian, Papuan) and frames personal DNA within human migration history.

About This Calculator

**Global Ancestry K45 — what it analyzes** This calculator decomposes an individual's genome into up to 45 modeled components using a curated panel of 33 modern and regionally informative reference populations. It measures proportions of shared genetic ancestry across Africa, Europe, West and Central Asia, South and East Asia, Oceania and the Americas to reveal fine-grained regional signals rather than broad continental labels. **Who it's designed for** - Genetic genealogy enthusiasts and adoptees seeking more precise regional clues - Researchers and students comparing population structure or admixture patterns - Anyone curious about how recent and ancient migrations shaped their DNA **What insights you can gain** - Percentage breakdowns of ancestry linked to specific regions (e.g. West Africa, Anatolia/Caucasus, Baltic, Persia/Mesopotamia, Southern Indian Subcontinent, Papuan) - Detection of minor components that signal historical contacts (e.g. Siberian, Finno‑Ugric, North Amerindian) - A nuanced view of European substructure (Basque, Sardinian, North Italy, Iberian, Scandinavian, England) **Historical and genetic context** Modern human genomes are mosaics of lineages shaped by repeated migrations, isolations and admixture events — Out‑of‑Africa dispersals, the spread of agriculture, steppe migrations, maritime contacts and prehistoric colonizations of Oceania and the Americas. K45 uses contemporary reference panels to map these echoes onto individual genomes, helping to place personal ancestry into that global story. **Why this calculator is valuable** - High resolution across underrepresented regions (e.g. North East Africa, Tibeto‑Burmese, South Central Asia) - Balanced set of 33 references for both large continental groups and fine regional subgroups - Actionable clues for follow‑up genealogical research without overclaiming precision **Interpretation note** Results are model-based estimates dependent on reference choices and are most informative as

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

How It Works

  • Your DNA is compared to 45 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
