Tolan K7 M1

Tolan K7 M1 — Global 7‑way Admixture (Modern Era)

This calculator estimates the proportional ancestry of an individual against seven modern reference clusters. Using a K=7 model (M1), it compares your genotype to curated reference populations and returns percentages for: North‑Euro, Mediterranean, Caspian‑Sea, N‑Africa & Middle‑Eastern, Africa (Sub‑Saharan), SE‑Asia, and NE‑Asia.

What it analyzes

• Genome‑wide allele frequencies to infer relative contributions from seven broad regional components.
• Signals that reflect both recent gene flow (within the past few hundred years) and deeper population structure shaped by migrations and isolation.

Who it’s for

• Individuals curious about their genetic heritage worldwide.
• Amateur and professional genealogists seeking population‑level context.
• Researchers and students needing a clear, interpretable K=7 baseline for comparative analyses.

Insights you can gain

• A clear numeric breakdown of continental and regional ancestry proportions.
• Clues about likely historical interactions (e.g., Eurasian steppe influence, Mediterranean admixture, African or East Asian inputs).
• A starting point to explore migration routes, admixture events, and regional genetic continuity.

Historical and genetic context

Each reference cluster represents broad, real‑world population patterns: North‑Euro (northern/central Europe and steppe‑derived signals), Mediterranean (southern Europe and Anatolia), Caspian‑Sea (Caucasus/Iranian plateau influences), N‑Africa & Middle‑Eastern (Levantine and Maghreb affinities), Africa (sub‑Saharan ancestries), SE‑Asia (Southeast Asian and Austronesian links), and NE‑Asia (East Asian/Siberian heritage). These components reflect millennia of migrations — from prehistoric expansions to recent trade and conquest — but are simplified models of complex history.

Why it’s valuable

• Fast, intuitive overview of where your genetic ancestry is most similar today.
• Useful baseline for comparing results
