(Star Trek: First Contact; TNG: Q Who) The Borg originated in the Delta Quadrant, (Star Trek: First Contact; VOY: Dark Frontier, Dragon's Teeth) where they already existed by 1484. At that time, only a handful of star systems had been assimilated by them and they had many encounters with the Vaadwaur.

DQ is made up of two different subunits to form an Î±Î²-heterodimer. Each subunit is encoded by its own gene (a coding locus). The DQ Î± subunit is encoded by the HLA-DQA1 gene and the DQ Î² subunit is encoded by the HLA-DQB1 gene. Both loci are variable in the human population (see regional evolution).
