Description

Helgi Hilmarsson leads a seven-author team presenting Gnomix in 2026, software that labels the ancestry of each DNA segment in people and animals with mixed heritage. Local ancestry inference powers studies of population history and ancestry-linked traits, yet older methods scale badly to biobank-sized data, deep time, and many source populations.

Gnomix bundles several inference methods that beat existing tools on both accuracy and speed, with shareable trained models that expose no private training genomes. A companion tool, Gnofix, corrects phasing errors quickly. Tests on worldwide human and dog genomes dated ancient New World segments in the Xoloitzcuintli dog breed back over 100 generations, showing the fine resolution achieved.
