MDLP World 22
MDLP World 22 — Global Modern+Ancient Admixture
A 22-component admixture model that blends modern and ancient reference proxies to reveal fine-scale global ancestry. Ideal for genealogists, researchers and curious users, it quantifies regional and prehistoric signals (Neolithic, Mesolithic, Siberian, Austronesian, Amerindian, African, Melanesian) to illuminate migration history and complex admixture patterns.

MDLP World 22 — Modern+Ancient Admixture Model
MDLP World 22 analyzes autosomal DNA using a 22-source reference panel that mixes modern and ancient proxies to reveal fine-scale global ancestry. The model quantifies how much of your genome matches diverse ancestral components such as Atlantic Mediterranean Neolithic, North-European-Mesolithic, Indo-Iranian, Austronesian, Melanesian, Pygmy, and multiple Amerindian, Siberian and African lineages.
Who this is for:
- Genetic genealogists and ancestry enthusiasts seeking detailed regional breakdowns
- Researchers and students comparing modern/ancient signals
- Anyone curious about migration histories and deep regional affinities
What you learn:
- Percent contributions from 22 reference populations spanning Eurasia, Africa, Oceania and the Americas
- Signals of ancient demography (e.g., Neolithic farmer, Mesolithic hunter-gatherer, Paleo-Siberian and Austronesian inputs)
- Modern admixture patterns from recent migrations and long-range contacts
Historical and genetic context: The MDLP World 22 model combines modern population samples with proxies for ancient groups to provide a bridge between recent population structure and deeper prehistory. It highlights processes such as the spread of farming across the Mediterranean, Siberian and Beringian links to the Americas, Austronesian expansion into Island Southeast Asia and Oceania, and sub-Saharan and Pygmy diversity in Africa.
Why it’s valuable:
- High-resolution, globally focused panel with both modern and ancient components
- Helps disentangle overlapping signals (e.g., distinguishing Atlantic Mediterranean Neolithic from North-European-Mesolithic)
- Useful as a comparative tool alongside other calculators and archaeological records
Caveats: Like all admixture models, results are model-dependent and approximate. Use MDLP World 22 as an informative lens — not a definitive pedigree — to explore your genetic ties to global human history.

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-22 אוכלוסיות ייחוס שנבחרו בקפידה כדי לבחון דמיון גנטי.
איך הניתוח עובד?
- הניתוח משווה את ה-DNA ל-22 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
