Description
DNA Genics World K38 (without Jewish populations) is an autosomal admixture calculator designed to estimate the proportional genetic ancestry of modern individuals using a globally distributed reference panel. It models an individual's genome as a mixture of genetic components derived from 35 curated reference populations spanning Europe, West Asia, Central and East Asia, South Asia, Africa, the Americas, and Oceania. This version intentionally omits discrete Jewish reference groups so users can explore broad continental and regional affinities without those specific clusters.
What it analyzes: the calculator compares genome-wide SNP data to the reference panel and reports relative contributions from component populations (e.g., Northwest European, West African, Mesoamerican and Andean, Papuan, South Asian). Results highlight shared ancestry proportions that reflect recent and deep population history, admixture events, and regional affinities.
Who it’s for: genetic genealogists, population geneticists, anthropologists, and curious individuals seeking a clear, interpretable snapshot of where an individual’s ancestry most closely aligns on a global scale. It is optimized for modern DNA datasets and can provide meaningful signals for people with mixed heritage or primarily single-region ancestry.
Insights and context: users will learn proportional ancestry breakdowns, detect minor ancestry components, and gain context for historical migrations—such as Eurasian steppe movements, African dispersals, Austronesian expansion, or peopling of the Americas. The calculator emphasizes population structure and shared drift rather than direct genealogical matches.
Why it’s valuable: by using a wide, geographically diverse reference panel, the K38 model provides a balanced, interpretable view of global ancestry while avoiding confounding from Jewish-specific clusters. It is a practical tool for hypothesis generation, comparative analyses, and educational exploration of human ge

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 38 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 38 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
