Tolan K13 M2
Tolan K13 M2 — Modern 13-way admixture calculator
Quickly estimate ancestry proportions across 13 modern reference populations (West/East Europe, South Med, Caucasus, Arabia, Siberia, Central Asia, India, SE Asia, West/East Africa, Oceania, East Asia). Designed for global users, it provides clear, interpretable percentages to explore recent migration, admixture signals, and genealogical context.

Tolan K13 M2 — Modern 13-way Admixture Calculator
This calculator analyzes an individual's genome to estimate proportions of ancestry across 13 modern reference populations. It is built for worldwide use and designed to give both casual users and researchers a clear, interpretable breakdown of recent ancestry components. Outputs are expressed as percentage contributions to reflect likely genetic input from each region over the last few thousand years.
What it analyzes
- Genome-wide single-nucleotide variation compared to 13 reference clusters
- Relative affinity to modern population profiles (not ancient samples)
- Patterns consistent with recent admixture, migrations, and regional gene flow
Reference populations
- A: West Europe
- B: East Europe
- C: South Mediterranean
- D: Caucasus
- E: Arabia
- F: Siberia
- G: Central Asia
- H: India
- I: South-East Asia
- J: West Africa
- K: East Africa
- L: Oceania
- M: East Asia
Who it's for
- Individuals exploring family origins and migratory background
- Genetic genealogy hobbyists seeking regional resolution
- Researchers needing a compact modern admixture profile for comparative work
Insights you can gain
- Proportional ancestry estimates that highlight major regional contributors
- Detection of expected and unexpected admixture signals (e.g., Eurasian–African mixtures)
- Context for genealogical records and historical migration hypotheses
Historical and genetic context
This model emphasizes modern population structure shaped by historic migrations, trade networks, and recent gene flow rather than deep Paleolithic lineages. It is most informative for events in the Holocene and late prehistory through modern times.
Why it’s valuable
- Clear, reproducible breakdown into 13 interpretable components
- Useful starting point for deeper analyses (local ancestry, haplogroups)
- Balances resolution and interpretability for a global audience
Limitations
- Reference clusters are simplifications of continuous human

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-13 אוכלוסיות ייחוס שנבחרו בקפידה כדי לבחון דמיון גנטי.
איך הניתוח עובד?
- הניתוח משווה את ה-DNA ל-13 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
