Global Ancestry K39
Global Ancestry K35 — A high-resolution modern admixture calculator that estimates proportional ancestry against 35 global reference populations. Ideal for users worldwide who want detailed regional breakdowns (Africa, Europe, Asia, Americas) and comparative affinity scores, while excluding Jewish-specific reference clusters. Sensitive, scientific, and designed for exploration, not medical diagnosis.

Global Ancestry K35
This calculator is a high-resolution, modern-era admixture model designed to estimate the proportional ancestry of individuals against a broad, globally distributed set of reference populations — with Jewish-specific reference groups intentionally excluded. "K39" denotes a 39-component labeling strategy that provides fine-scale resolution across continents using contemporary population panels.
What it analyzes
- Proportional ancestry across diverse regional components (Africa, Europe, Asia, the Americas).
- Affinity and similarity to 35 curated reference populations such as West African, East African, Basque, Scandinavian, Han Chinese, Japanese, Native American subgroups, South Asian clusters, Middle Eastern groups, and more.
- High-resolution signals that highlight recent and ancient admixture patterns visible in modern genomes.
Who this is for
- Individuals worldwide seeking a detailed, population-level breakdown of their genetic ancestry.
- Researchers and genealogists wanting a comparative tool that emphasizes broad global structure without Jewish reference clusters.
- Users interested in regional affinities, not medical or identity determinations.
Insights you can gain
- Percentage breakdowns of ancestral contributions from specific regions and populations.
- Identification of mixed heritage signals and likely continental/regional sources.
- A contextual view of how modern populations relate genetically across Eurasia, Africa, and the Americas.
Historical and genetic context
Human genetic variation reflects migration, isolation, and mixing over millennia. This model captures both deep population structure (e.g., hunter-gatherer and Eurasian lineages) and recent gene flow between neighboring regions (e.g., Mediterranean, South Asian, and African coastal exchanges).
Why this calculator is valuable
- Provides clear, interpretable ancestry proportions with high geographic detail.
- Useful for comparati

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-39 אוכלוסיות ייחוס שנבחרו בקפידה כדי לבחון דמיון גנטי.
איך הניתוח עובד?
- הניתוח משווה את ה-DNA ל-39 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
