Global Ancestry K45
Global Ancestry K45 maps your genome to a high‑resolution panel of 33 reference populations to reveal fine regional ancestry across Africa, Europe, Asia, Oceania and the Americas. Ideal for genealogists, researchers and curious users, it highlights subtle subcontinental signals (e.g. Anatolia, Persia, Finno‑Ugric, South Indian, Papuan) and frames personal DNA within human migration history.

Global Ancestry K45 — what it analyzes
This calculator decomposes an individual's genome into up to 45 modeled components using a curated panel of 33 modern and regionally informative reference populations. It measures proportions of shared genetic ancestry across Africa, Europe, West and Central Asia, South and East Asia, Oceania and the Americas to reveal fine-grained regional signals rather than broad continental labels.
Who it's designed for
- Genetic genealogy enthusiasts and adoptees seeking more precise regional clues
- Researchers and students comparing population structure or admixture patterns
- Anyone curious about how recent and ancient migrations shaped their DNA
What insights you can gain
- Percentage breakdowns of ancestry linked to specific regions (e.g. West Africa, Anatolia/Caucasus, Baltic, Persia/Mesopotamia, Southern Indian Subcontinent, Papuan)
- Detection of minor components that signal historical contacts (e.g. Siberian, Finno‑Ugric, North Amerindian)
- A nuanced view of European substructure (Basque, Sardinian, North Italy, Iberian, Scandinavian, England)
Historical and genetic context
Modern human genomes are mosaics of lineages shaped by repeated migrations, isolations and admixture events — Out‑of‑Africa dispersals, the spread of agriculture, steppe migrations, maritime contacts and prehistoric colonizations of Oceania and the Americas. K45 uses contemporary reference panels to map these echoes onto individual genomes, helping to place personal ancestry into that global story.
Why this calculator is valuable
- High resolution across underrepresented regions (e.g. North East Africa, Tibeto‑Burmese, South Central Asia)
- Balanced set of 33 references for both large continental groups and fine regional subgroups
- Actionable clues for follow‑up genealogical research without overclaiming precision
Interpretation note
Results are model-based estimates dependent on reference choices and are most informative as

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 45 من المجموعات السكانية المرجعية المختارة بعناية لاستكشاف أوجه التشابه الجيني.
كيف يعمل التحليل؟
- يقارن التحليل حمضك النووي بعدد 45 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
