  1. a2,935 OGS1.2 models are classified with strong homology to transposon proteins during OGS2 work, 385 models with expression and other insect homology but also transposon homology were retained in OGS2 “good” model set
  2. b5,763 additional genes of OGS2 have significant protein homology, but are not assigned as orthologs in OrthoMCL orthology analysis, 3,454 of 24,388 “good” models lack significant homology, but have expression evidence
