World and American Breakdown K28

**World and American Breakdown K28** — A modern, fine-scale admixture calculator comparing your DNA to 28 globally and regionally informed reference populations. It emphasizes Indigenous American substructure while resolving European, African, Middle Eastern, Asian and Oceanian contributions. Ideal for genealogists, adoptees, and researchers seeking clearer historical and geographic ancestry insights.

About This Calculator

**World and American Breakdown K28 — Modern global admixture calculator** This calculator analyzes genome-wide patterns of genetic ancestry by comparing a tested genotype to a curated panel of 28 reference populations from across the globe, with dense representation of Indigenous American groups. It quantifies proportional ancestry from sources such as Cree, Raramuri, Pima, Zapoteco, Mixteco, Nahua, Maya, Quechua, Karitiana, Surui, multiple European clusters, African regions, Middle East, South and East Asia, Southeast Asia, Oceania and others to produce a refined breakdown relevant to modern populations. **Who it’s for** - Genealogy enthusiasts, adoptees, and family history researchers - Population geneticists and students seeking comparative context - Anyone curious about complex ancestry in the Americas and worldwide **What you’ll learn** - Estimated proportions from 28 reference groups, highlighting fine-scale Indigenous American structure and global contributions - Signals of colonial-era admixture (European, African, and Middle Eastern inputs) and earlier migrations (Asian and Oceanian) where present - Geographic and historical context to help interpret mixed ancestries **Why this matters** - Many global calculators aggregate Indigenous American ancestry into a single category; K28 resolves multiple autochthonous groups to reveal regional Indigenous substructure - Useful for distinguishing nearby European clusters (Northern, Eastern, Southwest, Western) and African regional contributions - Helps translate genetic estimates into historical narratives: migration corridors, colonization events, and recent admixture patterns This tool prioritizes transparency: reference populations are named and geographically anchored, and results should be interpreted as statistical estimates rather than definitive labels. Use alongside family history, archival records, and regional knowledge for the most meaningful insights.

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

How It Works

  • Your DNA is compared to 28 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
