Description
World and American Breakdown K28 is a modern-era admixture calculator that estimates ancestry proportions across 28 curated reference populations, with particular resolution for Indigenous American groups. It translates genome-wide genotype data into a proportional map of regional affinities — from Cree, Raramuri, Pima and other Native American lineages, through Amazonian and Andean groups, to major continental blocks such as West, East and North Africa, multiple European clusters, Middle Eastern, South and East Asian, Southeast Asian, and Oceania. "K28" denotes a model built from 28 discrete reference clusters designed to capture both fine-scale Native American structure and broad global components.
This tool is intended for a worldwide audience: genealogists, ancestry enthusiasts, population geneticists, educators, and anyone curious about their genetic origins. It is especially useful for people with American ancestry who wish to distinguish between different Indigenous regional signals (e.g., Andean vs. Mesoamerican vs. Amazonian vs. Northern First Nations) as well as for users who want a balanced global context for those signals.
Users receive percent-based admixture estimates and regional affinity signals that can clarify ancestral contributions, reveal hidden or minority ancestries, and suggest historical processes such as migration, colonization, and population continuity. The calculator places results into genetic and historical perspective, explaining how drift, founder effects, and post-contact admixture can shape modern profiles.
Why it’s valuable: K28 combines targeted reference sampling of Indigenous American populations with comprehensive global coverage to improve interpretability for people with mixed ancestries. It helps bridge personal curiosity and academic insight while providing clear caveats: results are probabilistic, dependent on reference panels and marker sets, and should be combined with documented genealogy and other genetic analyses

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
Key Points
- Your DNA is compared to 28 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
