Admixture Calculator

Hybrid K20

Hybrid K20 (Ancient) estimates deep ancestral proportions by comparing genomes to 20 global and ancient reference populations—from Anatolian and Iranian farmers, European hunter-gatherers and Caucasus groups, to diverse African, South Asian, East Asian, Oceanian, Siberian, and Native American lineages. Designed for researchers and enthusiasts, it provides clear, interpretable snapshots of ancient population affinities and migration signals to support exploratory and comparative analyses.

About This Calculator

Hybrid K20 (Era: Ancient) is an admixture calculator designed to resolve deep, globally distributed ancestral components by comparing a sample to twenty carefully chosen reference populations spanning Africa, Europe, West and South Asia, East Asia, Oceania, the Americas, and ancient Anatolian and Iranian farmers. It analyzes genome-wide ancestry proportions to reveal how much genetic contribution a tested individual or ancient sample derives from long-diverged groups such as EHG (Eastern Hunter-Gatherers), ANF (Anatolian Neolithic Farmers), Ganj Dareh (early Iranian farmers), Caucasian lineages, diverse African groups (Yoruba, Luhya, Gambian, Mbuti Pygmies), South Asian and Dravidian-associated references (Irula, Kalash), Middle Eastern Bedouin, East and Southeast Asian sets (Japanese, Igorot), Oceanian and island components (Papuan, Onge), Siberian inputs, and multiple Native American representatives (Pima, Peruvian, Surui, Karitiana). Who it’s for: Hybrid K20 is targeted at population geneticists, archaeogeneticists, advanced hobbyists, and anyone working with ancient or modern genomes who wants a compact, interpretable snapshot of deep ancestral affinities. It is particularly useful when seeking to place a sample in a broad ancient context—detecting traces of hunter-gatherer, early farmer, Sub-Saharan, South Asian, East Asian, Oceanian, Siberian, or Native American ancestry. Insights provided: proportional ancestry breakdowns, relative affinities to ancient farmer and hunter-gatherer sources, and detection of subtle non-local inputs. The calculator highlights migration signatures, continuity versus replacement scenarios, and comparative signals useful for hypothesis generation and cross-sample comparisons. Why it matters: By combining geographically and temporally informative references, Hybrid K20 helps translate raw genotype data into clear narratives about ancient population structure and movement. It is a practical, accessible tool that complements formal

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 20 carefully selected ancient populations as references, allowing for a detailed breakdown of your genetic heritage.

How It Works

Your DNA is compared to 20 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
