Global Ancestry K30 2023
**Global Ancestry K30 2023** — A modern K=30 admixture calculator that estimates your proportional ancestry against 26 curated reference populations. Ideal for individuals, genealogists, and researchers, it reveals fine-grained regional affinities (e.g., Anatolia-Caucasus, Sardinian, North British Isles) while balancing resolution and interpretability for robust, actionable ancestry insights.

About This Calculator
**Global Ancestry K30 2023 — Modern-era K=30 admixture calculator**
This calculator analyzes an individual's genome against a curated panel of 26 reference populations to estimate proportional ancestry components using a K=30 model optimized for modern global diversity (2023). It decomposes genetic variation into discrete components that reflect recent and deep ancestral affinities across Africa, Eurasia, the Americas and Oceania.
**What it analyzes**
- Autosomal single-nucleotide variation across the genome to infer proportional ancestry for 30 components trained on diverse modern and regionally informative reference groups.
**Who it's designed for**
- Individuals seeking a nuanced global ancestry overview
- Genealogists and family historians exploring multi-regional admixture
- Researchers and students needing a clear, interpretable K30 admixture profile
**Insights you can gain**
- Relative contribution from major regional sources (e.g., West African, Anatolia-Caucasus, North and Central European)
- Distinguishing components that cluster with specific historical populations (e.g., Sardinian, Ashkenazi Jewish, Scandinavia)
- Detecting complex mixed ancestries, recent admixture signals, or subtle regional affinities not visible in coarse models
**Historical and genetic context**
- The K30 configuration captures both broad continental structure and finer subcontinental partitions that reflect major migrations, expansions, and long-term regional isolation (e.g., Iranian Plateau, North east Asia, Central Indian subcontinent).
- It is built on modern reference panels; interpretations should consider recent population movements and local demographic history.
**Why this calculator is valuable**
- Balances resolution and interpretability: more detailed than low-K models yet designed to avoid overfitting common in very high-K approaches.
- Useful for comparative analysis: run against other K models or reference sets to triangulate ancestry conclusions.

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 30 carefully selected modern populations as references, allowing for a detailed breakdown of your genetic heritage.
How It Works
- Your DNA is compared to 30 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
