About This Calculator

**Global Ancestry K23 2017** is a high-resolution admixture calculator that estimates an individual’s genetic ancestry using a model of 23 ancestry components (K=23) derived from 161 curated reference populations worldwide. It compares your genotype to a broad panel spanning Europe, the Near East, North Africa, Sub‑Saharan Africa, South and Southeast Asia, East Asia, Siberia, the Americas and Oceania to report proportional affinities and regional signals. Who this calculator is for: - Researchers seeking a compact, replicable K=23 overview of global ancestry - Genealogists and adoptees exploring multi‑regional roots - Enthusiasts curious about fine‑scale continental and subcontinental ancestry What this calculator analyzes: - Genome‑wide allele frequency patterns matched to 23 modelled components - Relative contributions from 161 modern reference populations (e.g., Western and Eastern Europe, Levant, Arabian Peninsula, North Africa, South Asia, East Asia, Siberia, Indigenous American groups, Oceania, and diverse African populations) Insights you can gain: - Percent‑level breakdowns of major ancestry components and regional affinities - Signals of recent admixture versus older shared ancestry - Clues to migratory and historical contacts (e.g., Eurasian steppe, Mediterranean, Trans‑Saharan interactions) Context and limitations: - K=23 is a modern, statistical model — components are abstractions that summarize genetic structure, not “pure” historical populations. - Results depend on reference sampling, allele frequencies, and quality of input genotype data. Interpret as probabilistic affinities, not definitive identities. Why this calculator is valuable: - Combines broad geographic coverage (161 populations) with a compact, interpretable K=23 framework to reveal subtle multi‑regional patterns - Useful as an exploratory tool alongside haplogroup and segment‑based analyses for building hypotheses about ancestry How to read results: look for dominant components, sec

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

How It Works

  • Your DNA is compared to 23 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
