Admixture Calculator

MDLP World Ancient Roots K18

**MDLP World Ancient Roots K18** is an ancient-era admixture calculator that estimates deep ancestral affinities across 18 global components. It reveals modeled proportions of ancient lineages—from Eurasian, African, and American roots to Arctic and Austronesian signals—helpful for researchers, genealogists, and curious users seeking historical genetic context. Results show affinity, not definitive ethnicity.

About This Calculator

**MDLP World Ancient Roots K18** is an ancestry admixture calculator designed to profile deep, ancient genetic affinities across a global set of 18 modeled components. Using allele-frequency comparisons to a curated panel of ancient and long-standing population proxies, this tool estimates the proportional contributions of ancestral lineages that shaped modern and historical populations around the world. What this calculator analyzes: - Genome-wide affinities to 18 ancient/root components including **Caucasian, Melano-Austronesian, Volga-Uralic, East_Siberian, West_Siberian, South_Central_Asian, South_Indian, North_West_European, Sami-Finnic, South_East_Asian, Archaic_African, Mediterranean, Arctic, Afroasiatic, East_European, Roma, East_African,** and **Amerindian**. - Relative proportions that reflect modeled genetic similarity to those reference groups rather than strict population identities. Who it's for: - Researchers, students, and enthusiasts exploring ancient population structure and migration patterns. - Genealogy hobbyists seeking broader historical context for family origins. - Anyone curious about how deep ancestral roots and prehistoric contacts contributed to present-day diversity. Insights you can gain: - A simplified map of likely ancient affinities and mixture signals across continents. - Evidence of prehistoric migrations (e.g., Eurasian steppe inputs, Austronesian dispersals, African/Archaic connections) and regional continuity. - Comparative context to place your results among major ancient genetic clusters. Historical and genetic context: This model draws on the idea that modern genomes are mosaics of ancient lineages shaped by migration, isolation, and local admixture. The 18 components represent broad, temporally deep ancestral pools used as proxies to reconstruct those historical threads. Why this calculator is valuable: - Offers a globally scoped, ancient-focused breakdown that complements modern-focused tests. - Helps translate comple

Understanding Admixture Analysis

Learn how admixture calculators work and how to interpret your results

What is Admixture Analysis?

Admixture analysis is a method used to estimate your genetic ancestry by comparing your DNA to reference populations from around the world. Think of it as creating a recipe of your genetic makeup, where the ingredients are different ancestral populations.

This calculator uses 18 carefully selected ancient populations as references, allowing for a detailed breakdown of your genetic heritage.

How It Works

Your DNA is compared to 18 reference populations
Ancient populations are used as genetic references
Results show your genetic similarity to these populations
More accurate with a diverse reference panel

Understanding Your Results

Your results will show percentages of genetic similarity to these reference populations. Remember these important points:

Results reflect genetic similarity, not direct ancestry
Ancient populations are used as references
Percentages indicate relative genetic contribution
Results are estimates based on available reference data
