GedrosiaDNA World 25
GedrosiaDNA World 25 — Modern global admixture calculator
Compare your autosomal DNA to a 27-population modern reference panel and receive a clear, 25-component breakdown of global ancestry. Ideal for genealogy enthusiasts and researchers, it highlights regional affinities and historical migration signals (Steppe, EEF, Siberian, Oceanian, African, Native American, etc.) with accessible interpretation and caveats.

GedrosiaDNA World 25 — Modern global admixture calculator
GedrosiaDNA World 25 analyzes an individual's autosomal DNA against a modern reference panel to estimate ancestry proportions across the globe. Using 27 curated reference populations that span East and West Eurasia, Africa, Oceania, and the Americas, the calculator decomposes a genome into fine-grained components (World 25) to reveal regional affinities and historical admixture signals.
Who it’s for:
- Genetic genealogy enthusiasts who want context beyond continental labels
- Researchers seeking a compact, interpretable breakdown of global ancestry
- People curious about historical migrations reflected in their DNA
What you get:
- A percentage breakdown across 25 global components derived from 27 reference populations (e.g., East Asian, Siberian, Steppe, Early European Farmer, Near Eastern, South Asian, various African hunter-gatherer and Bantu-lineage references, Oceanian and Papuan, and multiple Native American clusters)
- Visual and numerical summaries highlighting dominant ancestries and minor signals
- Interpretive notes that connect components to known historical events (e.g., Neolithic farmer expansions, Steppe migrations, Austronesian dispersals, Native American founding waves)
Historical and genetic context: This calculator contextualizes modern genomes within major prehistoric and historic population movements. Components like EEF (Early European Farmers), W_STEPPE/E_STEPPE (Steppe ancestries), SHG/WHG hunter-gatherer signals, and multiple African and Oceanian references reflect lineages shaped by migrations, admixture, and founder effects over millennia.
Why it’s valuable:
- Global scope: meaningful resolution across all inhabited continents
- Balanced detail: enough components to highlight subtle mixtures without overwhelming jargon
- Modern reference panel: tuned to contemporary population structure for results relevant to living individuals
A note on interpretation: Results are statist

ما تحليل التركيب الجيني؟
يقارن تحليل التركيب الجيني حمضك النووي ببيانات مجموعات سكانية مرجعية من أنحاء العالم. ويقدّر مدى التشابه مع المكوّنات المرجعية التي يتألف منها النموذج.
تستخدم الحاسبة 25 من المجموعات السكانية المرجعية المختارة بعناية لاستكشاف أوجه التشابه الجيني.
كيف يعمل التحليل؟
- يقارن التحليل حمضك النووي بعدد 25 من المجموعات السكانية المرجعية
- يستخدم التحليل مجموعات سكانية مرجعية من الفترات المعروضة.
- توضّح النتائج مدى التشابه الجيني مع هذه المجموعات
- تؤثر ملاءمة المراجع وتنوّعها في جودة المقارنة
فهم النتائج
تعرض النتائج نسبًا مقدّرة ضمن نموذج المقارنة بالمجموعات المرجعية. ضع النقاط التالية في الاعتبار:
- تعبّر النتائج عن التشابه الجيني ولا تثبت النسب المباشر
- تعتمد المقارنة على المجموعات المرجعية المدرجة في الحاسبة.
- تبيّن النسب الوزن النسبي لكل مكوّن في النموذج
- النتائج تقديرات تستند إلى البيانات المرجعية المتاحة
