MDLP K9c
MDLP K9c is a nine-component global admixture calculator that estimates ancestry proportions from autosomal SNP data across African, Amerindian, Caucasian, European, Indian, Near East, Papuan, Southeast Asian, and Siberian reference groups. Designed for worldwide users—from genealogists to researchers—it offers an accessible, comparative view of major ancestral affinities and migration-related signals while remaining straightforward to interpret.

MDLP K9c is a modern, nine-component autosomal admixture calculator designed to provide a clear, comparative view of global ancestry. Using genotype data from SNP microarrays, it estimates the proportional contribution of nine broad reference populations—African, Amerindian, Caucasian, European, Indian, Near East, Papuan, Southeast Asian (SEA), and Siberian—to an individual's genome. The calculator is intended for a worldwide audience: genetic genealogy enthusiasts, adoptees, family historians, population geneticists, and anyone curious about their deep ancestral affinities.
By translating tens of thousands of genetic markers into nine intuitive components, MDLP K9c reveals which large-scale ancestries dominate a profile and which are present at lower levels. Users gain insights into continental and subcontinental connections, helping to contextualize family stories, migration histories, and regional affinities. The nine components reflect major prehistoric and historic population movements—Out-of-Africa dispersals, peopling of the Americas, Eurasian farmer and steppe expansions, South Asian and Near Eastern demography, Austronesian and Papuan dispersals, and Siberian gene flow—so results can be interpreted alongside archaeological and linguistic evidence.
MDLP K9c is valuable because it balances resolution with accessibility: fewer components reduce overfitting and simplify interpretation while retaining enough granularity to detect meaningful regional signals. It is useful for cross-tool comparisons, providing a stable framework for tracking how ancestry proportions change across different calculators. Users should note that component labels are broad approximations and that accuracy depends on the quality and representativeness of reference samples. MDLP K9c is best used as a comparative, exploratory tool that complements genealogical records and other genetic analyses, offering a global perspective on ancestry that is both scientifically grounded and easy to u
אוכלוסיות ייחוס
האוכלוסיות שהמחשבון משתמש בהן כייחוס גנטי
9 אוכלוסיות ייחוס
African:
Dive into the rich tapestry of African ancestry, spanning from the rolling savannahs to the expansive deserts and lush rainforests. This component reflects the cradle of humanity, where diverse cultures, languages, and biological traits have evolved over millennia, contributing profoundly to the global genetic and cultural landscape.Amerindian:
The Amerindian ancestry component encapsulates the rich heritage of the indigenous peoples of North, Central, and South America. This lineage reveals the deep-rooted traditions and adaptations of societies that have flourished across diverse environments, from the Arctic cold to the Amazonian heat, long before European contact.Caucasian:
Explore the Caucasian ancestry, rooted in the rugged terrains between the Black and Caspian Seas. This region is a melting pot of cultures, languages, and genetic lineages, reflecting centuries of trade, conquest, and cultural exchange that have shaped the identities of the diverse peoples inhabiting this ancient crossroads.European:
The European ancestry component spans a continent rich in history and cultural evolution, from the ancient Greeks and Romans to the modern era. This lineage reflects a journey through time, where complex societies developed strong traditions in art, science, and philosophy that have fundamentally shaped Western civilization.Indian:
Discover the Indian ancestry component, characterized by its vast array of cultures, religions, and languages that have mingled on the Indian subcontinent. From the Himalayas to the southern coasts, this heritage is a testament to the region's role as both a birthplace of ancient civilizations and a dynamic player in modern global exchanges.Near East:
The Near East ancestry component covers the fertile crescent and beyond, an area pivotal in the history of civilization where farming, writing, and the first cities emerged. This lineage captures the essence of a region that has been a cultural and religious melting pot for millennia, influencing and influencing civilizations around the globe.Papuan:
Papuan ancestry highlights the distinct genetic and cultural evolution of the people in New Guinea and nearby islands. Living in one of the most biodiverse regions on Earth, the Papuans have maintained their traditions and languages through thousands of years, showcasing a profound connection to their environment.SEA (Southeast Asian):
Southeast Asian ancestry reflects a region shaped by its tropical climate and maritime geography, where a rich history of kingdom-building, trade, and cultural exchange flourishes. From the rice paddies of Vietnam to the islands of Indonesia, this component reveals the adaptive, diverse nature of the peoples in this vibrant area.Siberian:
Siberian ancestry conveys the adaptation of its peoples to the vast and harsh landscapes of northern Asia. This lineage captures the spirit of resilience of the nomadic tribes and settled communities who have thrived in the Arctic and sub-Arctic zones, navigating the challenges of extreme climates and remote geographies.
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-9 אוכלוסיות ייחוס שנבחרו בקפידה כדי לבחון דמיון גנטי.
איך הניתוח עובד?
- הניתוח משווה את ה-DNA ל-9 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
