Description

DNA Genics World K27 is a modern admixture calculator that evaluates genome-wide SNP data to estimate the proportional ancestry of an individual against a curated global reference panel. Using a multi-cluster K27 framework mapped to 21 geographically and historically informed reference populations (Africa East, Central African, North African, West African, Americas, Anatolia–Caucasus–Iranian Plateau, Central Asia, Central Indian Subcontinent, East Asia, East European, Southern Indian Subcontinent, Ashkenazi Jewish, Balkan, Finland, Iberian, North British Isles, North Italy, North and Central European, Sardinian, Scandinavia, Oceania), this tool translates raw genetic variation into a readable profile of regional affinities. Who it’s for: researchers, family historians, adoptees, citizen scientists and anyone curious about ancestral roots will find World K27 useful. It is designed to complement genealogical records and historical knowledge by providing quantitative ancestry proportions and highlighting connections to broad population clusters across Africa, Eurasia, the Americas and Oceania. What you learn: results show estimated percentage contributions from each reference population, helping to distinguish continental from regional mixtures, detect signals of recent admixture, and reveal deeper population relationships shaped by events such as Out-of-Africa dispersals, Neolithic farmer expansions from Anatolia, Steppe-related movements, Bantu and Austronesian spreads, and founder events in island or isolated groups (e.g., Sardinian, Ashkenazi, Oceania). Why it’s valuable: World K27 balances broad geographic coverage with regional detail, making it useful for hypothesis generation, comparative studies, and personal discovery. The calculator emphasizes transparency about limitations: outputs are statistical estimates influenced by reference selection, sample density and marker overlap, and do not provide clinical or identity determinations.

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 27 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 27 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
