World and Jewish Breakdown K28
World and Jewish Breakdown K28 — A modern-era admixture calculator optimized for Jewish individuals. It compares your DNA to 25 reference populations (11 Jewish subgroups plus regional groups like East-Med, Caucasus, North-African and West-European) to produce a fine-grained percentage breakdown. Ideal for genealogy, community research, and exploring historical admixture with clear, interpretable results.

World and Jewish Breakdown K28 — Modern-era Admixture Analyzer
This calculator estimates the proportional ancestry of an individual against a 28-cluster model (K28) tuned for modern populations, with special emphasis on Jewish communities. It compares your DNA to 25 reference populations — including 11 Jewish subgroups (e.g., Ashkenazi, Sephardic, Yemenite, Ethiopian-Jewish) and 14 regional groups (Anatolian, East-Med, Caucasus, West-European, North-African, South-Asian, West-Asian, etc.).
What it analyzes
- Genome-wide autosomal variation to produce percentage affinities to each reference population
- Fine-scale differences among Jewish groups and neighboring regional sources
- Signals consistent with historical migrations, conversions, trade routes and local admixture
Who it's designed for
- Jewish individuals curious about internal community structure and regional admixture
- Genealogists, family historians and community researchers investigating recent ancestry
- Researchers seeking a modern-era, Jewish-aware reference framework
Insights you can gain
- Quantified shares from distinct Jewish communities (e.g., Ashkenazi vs. Sephardic) and non-Jewish regional sources
- Detection of North-African, East-Med, Caucasus or South-Asian components that reflect historical contacts
- Context for endogamy, founder effects and admixture timing when combined with other tools
Historical and genetic context The Jewish diaspora spans millennia of migrations, conversions and local admixture. By contrasting multiple Jewish subgroups with surrounding populations, K28 highlights both shared Levantine heritage and community-specific inputs (e.g., North-African, Iberian, Central-Asian or Ethiopian signals) shaped by regional history.
Why this calculator is valuable
- Tailored reference panel: greater resolution for Jewish-related ancestry than broad global models
- Actionable outputs: clear percentage breakdowns suitable for personal reports or downstream analysis

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-28 אוכלוסיות ייחוס שנבחרו בקפידה כדי לבחון דמיון גנטי.
איך הניתוח עובד?
- הניתוח משווה את ה-DNA ל-28 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
