Description
Modern World K42 is a curated admixture calculator that estimates the modern ancestral composition of a DNA sample by comparing it to 42 carefully chosen reference populations from around the globe. Designed for genealogists, adoptees, ancestry enthusiasts, students and population researchers, this tool transforms genotype data into clear proportional affinities across major regions ā€” Africa, Europe, the Middle East, South and Central Asia, East and Southeast Asia, Oceania and the Americas ā€” with fine-grained subregional resolution. What it analyzes: Modern World K42 quantifies how much your DNA resembles each reference population (for example: Northern Africa, Balochistan, Anatolia and the Caucasus, Southeast Asia Austronesian, Melanesia, Native American Andean, and many European subgroups). The calculator highlights mixture signals that reflect recent and ancient migrations, such as Bantu expansions, North African and Near Eastern exchanges, Neolithic farmer and Indo-European impacts in Europe, Silk Road and Central Asian gene flow, Austronesian dispersals across Island Southeast Asia and the Pacific, and colonial-era admixture in the Americas. What you can learn: proportional ancestry estimates, primary regional affinities, and subtle secondary signals that suggest historical contacts or recent admixture. Results are useful for constructing hypotheses about family origins, guiding further genealogical research, or informing more detailed population studies. Why itā€™s valuable: The 42 reference populations are curated to balance geographic breadth and resolution, focusing on modern-era signatures that are relevant to contemporary genealogical questions. The interface emphasizes transparent, interpretable outputs and encourages responsible use: admixture estimates are probabilistic, depend on reference composition, and do not identify individualsā€™ specific ancestors. For best interpretation, combine admixture results with documentary genealogy, uniparental marker

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 42 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 42 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
