Global Ancestry K23 — Modern, worldwide admixture calculator
Global Ancestry K23 estimates the proportional ancestry of an individual using 23 modeled components derived from 22 geographically and historically informed reference populations. It is built to detect fine-grained regional signatures across Eurasia, Africa, the Americas, and Oceania in the context of modern human population structure.
What this calculator analyzes
- Genome-wide allele frequency patterns to infer percentage contributions from 22 reference clusters (Anatolian, Baltic, Central-Europe, East-Balkan, East-Med, Eastern-European, Finnish, North-West-European, South-Central-Europe, West-Balkan, West-Med, East-African, North-African, West-African, Central-Asian, East-Asian, South-Asian, South-East-Asian, South-Caucasus, West-Asian, Siberian-Central-Amerindian, South-Amerindian).
- Signals of recent and deep ancestry, distinguishing continental and sub-continental components.
Who it’s designed for
- Genealogy enthusiasts seeking regional breakdowns.
- Researchers and students exploring recent population structure and admixture.
- Individuals curious about how historical migrations shaped their genome across Eurasia, Africa, and the Americas.
Insights you can gain
- Percentage estimates of ancestral contributions from specific historical regions.
- Detection of mixed heritage (e.g., Eurasian–African–Amerindian admixture) and likely geographic sources.
- Clues to past migrations and contact events (Neolithic farmer expansions, Steppe ancestry pulses, Silk Road interactions, transatlantic movements).
Historical and genetic context
- Modern human populations reflect waves of migration, isolation and admixture: post-glacial recolonization, agricultural diffusion from Anatolia and the Near East, Bronze Age steppe movements, transcontinental trade and recent colonial-era gene flow. K23 frames individual genomes against these patterns using contemporary reference clusters.

הבנת ניתוח ההרכב הגנטי
כך פועלים המחשבונים, וכך קוראים את התוצאות
מהו ניתוח הרכב גנטי?
ניתוח הרכב גנטי משווה את ה-DNA לנתונים של אוכלוסיות ייחוס מרחבי העולם. הוא מעריך את מידת הדמיון לרכיבי הייחוס שמהם המודל בנוי.
המחשבון משתמש ב-23 אוכלוסיות ייחוס שנבחרו בקפידה כדי לבחון דמיון גנטי.
איך הניתוח עובד?
- הניתוח משווה את ה-DNA ל-23 אוכלוסיות ייחוס
- הניתוח משתמש באוכלוסיות ייחוס מהתקופות המוצגות.
- התוצאות מראות את מידת הדמיון הגנטי לקבוצות אלה
- ההתאמה של הייחוס והמגוון שלו משפיעים על איכות ההשוואה
הבנת התוצאות
התוצאות מציגות שיעורים מוערכים בתוך מודל ההשוואה לאוכלוסיות הייחוס. כדאי לזכור את הנקודות האלה:
- התוצאות מבטאות דמיון גנטי ואינן מוכיחות מוצא ישיר
- ההשוואה נשענת על אוכלוסיות הייחוס שכלולות במחשבון.
- השיעורים מראים את המשקל היחסי של כל רכיב במודל
- התוצאות הן אומדנים המבוססים על נתוני הייחוס הזמינים
