MDLP K12d
MDLP K12d is an ancient-era admixture calculator that estimates 12 deep ancestral components (Arctic, African, WHG, Siberian, EHG, SEA, CHG, SHG, Papuan, Natufian, Neolithic, ASI). Designed for global samples, it highlights prehistoric genetic contributions tied to hunter-gatherers, Neolithic farmers, and regional ancient populations—useful for enthusiasts, students, and researchers exploring deep ancestry.

MDLP K12d is an ancient-era admixture calculator that decomposes a DNA sample into 12 deep-time ancestral components derived from widely distributed reference groups. It estimates proportions of Arctic, African, Western Hunter-Gatherer (WHG), Siberian, Eastern Hunter-Gatherer (EHG), Southeast Asian (SEA), Caucasus Hunter-Gatherer (CHG), Southern Hunter-Gatherer (SHG), Papuan, Natufian, Neolithic, and Ancestral South Indian (ASI) ancestry. The model is designed for world-wide samples and is useful to anyone interested in understanding the deep, prehistoric layers of genetic heritage: hobbyist genealogists, population geneticists, students, and anyone curious how ancient migrations contributed to today’s genomes.
What this calculator analyzes: MDLP K12d compares an individual’s genetic markers to reference clusters that approximate ancient populations and returns a proportional breakdown. These components act as lenses on major prehistoric events — for example, the spread of Neolithic farming, movements of Eurasian hunter-gatherers, Steppe-related influences captured by EHG/CHG contrasts, and deep southern and Papuan/Southeast Asian signals in Asia and Oceania.
Insights users can gain: quantitative estimates of ancestral contributions linked to archaeological and population histories; patterns that suggest regional affinities, ancient admixture events, or continuity with specific prehistoric groups; and a framework to compare samples across regions or time. The calculator contextualizes results with a genetic narrative: Out-of-Africa dispersals, hunter-gatherer structure across Europe and Siberia, Neolithic farmer expansions, south and southeast Asian deep ancestry (ASI/SEA/Papuan), and Levantine/Natufian influences.
Why it’s valuable: MDLP K12d condenses complex population history into an accessible set of components that are informative for hypothesis generation, teaching, and comparative analyses. Caveats: component labels are simplified shorthand, estimates are
אוכלוסיות ייחוס
האוכלוסיות שהמחשבון משתמש בהן כייחוס גנטי
12 אוכלוסיות ייחוס
Arctic
- Indigenous peoples inhabiting the Arctic regions of the world, adapted to the cold climate and traditionally rely on hunting, fishing, and reindeer herding.
African
- Diverse group of populations native to the African continent, with a wide range of ethnic groups, languages, and cultures.
Western Hunter-Gatherer (WHG)
- Hunter-gatherer populations that inhabited Western Europe before the arrival of farmers from the Near East.
Siberian
- Indigenous peoples inhabiting Siberia, a vast region in northern Asia, with diverse ethnic groups traditionally practicing nomadic pastoralism and reindeer herding.
Eastern Hunter-Gatherer (EHG)
- Hunter-gatherer populations that inhabited Eastern Europe before the arrival of farmers from the Near East.
Southeast Asian (SEA)
- Diverse group of populations inhabiting Southeast Asia, a region of great cultural and linguistic diversity.
Caucasus Hunter-Gatherer (CHG)
- Hunter-gatherer populations that inhabited the Caucasus region before the arrival of farmers from the Near East.
Southern Hunter-Gatherer (SHG)
- Hunter-gatherer populations that inhabited Southern Europe before the arrival of farmers from the Near East.
Papuan
- Indigenous peoples inhabiting the island of New Guinea and surrounding islands, genetically distinct from other populations in Southeast Asia and Oceania.
Natufian
- Late Epipaleolithic culture in the Levant region of the Near East, semi-sedentary hunter-gatherers who lived in villages and practiced early forms of agriculture.
Neolithic
- Period of human history characterized by the transition from a hunter-gatherer lifestyle to a settled agricultural lifestyle.
Ancestral South Indian (ASI)
- Ancient population that contributed to the ancestry of modern South Asians, genetically distinct from the Ancient North Indians (ANI).
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-12 אוכלוסיות ייחוס שנבחרו בקפידה כדי לבחון דמיון גנטי.
איך הניתוח עובד?
- הניתוח משווה את ה-DNA ל-12 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
