Description
GedrosiaDNA World 25 is a modern-era autosomal admixture calculator that estimates an individual’s proportional ancestry against 27 curated global reference clusters. It quantifies contributions from broad and regionally specific sources — from East and West Eurasian steppe components (E_STEPPE, W_STEPPE) and Early European Farmers (EEF), to multiple African hunter-gatherer groups (SAN_PYGMY, MBUTI, C_AFRICAN_BIAKA, E_AFRICAN_HADZA), diverse Asian lineages (E_ASIAN, ALTAIAN, E_SIBERIAN, SE_ASIAN, PAPUAN, OCEANIAN) and Indigenous American branches (C_AMERINDIAN, S_AMERINDIAN, N_AMERINDIAN), as well as Near Eastern, South Asian (BALOCHI, S_INDIAN), North African, and Arctic clusters.
Designed for genealogists, population-genetics enthusiasts, researchers, and anyone curious about their multi-layered ancestry, this calculator provides a global perspective rather than region-limited snapshots. Users receive a breakdown of percentage ancestry by component, enabling insights into ancient migrations (Out-of-Africa dispersals, Neolithic farmer expansions, Eurasian Steppe movements, Austronesian and Papuan interactions, and the peopling of the Americas) and recent admixture patterns that shaped modern populations.
GedrosiaDNA World 25 is valuable because it combines fine-grained reference clusters with an accessible interpretation framework: it helps disentangle overlapping signals, highlights unexpected affinities, and suggests historical scenarios consistent with observed proportions. It’s especially useful for people with multi-regional heritage or for comparative studies across populations.
Limitations: results are model-dependent and reflect the chosen references and algorithms; they should be interpreted as probabilistic estimates rather than definitive pedigrees. For best context, combine results with uniparental markers, documented genealogy, and archaeological/ancient-DNA evidence. GedrosiaDNA World 25 is a powerful starting point for exploring the deep, layered

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 25 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 25 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
