Global Ancestry K27 2025
Global Ancestry K28 — High-resolution autosomal admixture
Discover the regional and continental composition of your DNA with a K28-style model mapped to 23 modern reference groups. Ideal for genealogists, adoptees, and researchers, it provides a clear proportional breakdown and historical context—highlighting migrations and mixtures that shaped your ancestry. Probabilistic, interpretable, and designed for exploration.

Global Ancestry K28 — Modern autosomal admixture at continental and regional resolution
This calculator analyzes your autosomal DNA and estimates the proportional ancestry you share with a curated set of modern reference populations. Using a high-resolution K28-style model tuned to 23 broad and regional groups, the tool places your genome on a continuum from continental-scale components (African, East Asian, European, Amerindian) down to regional clusters (Anatolian, Levantine, West Med, Horn of Africa, Siberian, Finnic, South Asian, etc.).
Who it’s for
- Genealogy enthusiasts and adoptees seeking detailed family origins
- Students and researchers comparing population structure in modern cohorts
- Anyone curious about how recent and ancient migrations shape personal ancestry
What insights you gain
- A proportional breakdown of ancestry across 23 modern reference groups
- Highlights of likely regional contributions (e.g., Anatolian farmer-related, Steppe-associated, West African, East African/ Horn signals)
- Context for unexpected components (historic trade routes, colonial-era admixture, long-distance migrations)
Historical and genetic context Human populations are the product of repeated migrations, isolates and mixtures: Out-of-Africa dispersals, Neolithic farming spread from Anatolia, Bronze Age steppe movements, Silk Road contacts, and more recent colonial and slave-trade-era exchanges. This calculator situates your DNA within that continuum using contemporary reference samples representing those geographic and historical legacies.
Why this calculator is valuable
- Balances broad continental categories with focused regional clusters for nuanced interpretation
- Designed for clarity: proportions are presented as interpretable components rather than deterministic labels
- Useful as a starting point for deeper research, genealogical triangulation, or curiosity-driven exploration
Notes: this is an ancestry inference tool, not a medical tes

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 27 من المجموعات السكانية المرجعية المختارة بعناية لاستكشاف أوجه التشابه الجيني.
كيف يعمل التحليل؟
- يقارن التحليل حمضك النووي بعدد 27 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
