LM Genetics Global K3 — Rapid, global three-way admixture model

This calculator projects a genotype onto a compact, global three-component (K=3) ancestry model trained on a broad reference panel that includes nine regional groups (Negroid, Sub‑Saharan African, Europeid, European, Middle Eastern, Caucasus, Mongoloid, East Asian, Native American). It summarizes complex worldwide diversity into three principal ancestry axes that reflect the deepest continental-scale structure.

What it analyzes

• Estimates the proportion of an individual's genome assigned to three major ancestry clusters derived from the nine reference populations.
• Uses a simplified model to highlight broad continental affinities and major admixture trends rather than fine-grained population assignments.

Who it's for

• Genealogy enthusiasts and curious individuals seeking a clear, easy-to-interpret summary of global ancestry.
• Researchers and educators needing a quick comparative view across world populations.

Insights you can gain

• Continental-scale ancestry proportions (e.g., African, West Eurasian, East Eurasian/Native American axes).
• Major admixture patterns such as recent mixed heritage or predominant regional affiliation.
• A starting point for deeper analysis with higher-K models or targeted regional panels.

Historical and genetic context

• Human genetic variation is shaped by ancient migrations (Out-of-Africa, Eurasian dispersals, peopling of the Americas) and more recent population movements. This K=3 model captures those broad separations while the nine reference groups anchor the clusters to familiar regional genomes.

Why this calculator is valuable

• Fast, interpretable, and well suited for global overviews where clarity matters. It provides a robust, low-resolution snapshot of ancestry that is ideal for comparison, teaching, and initial exploration.

Caveats

• Labels in the reference set reflect historical conventions and are used for anchoring; they do not define individual
