The definition of categories and patterns of gene pairs. On the basis of relative transcription direction, gene pairs are divided into three categories: (A) CDPG, gene transcribed in the same direction. (B) CPG, gene transcribed in the opposing direction but toward each other. (C) DPG, gene transcribed in the opposing transcription direction but toward distant directions. According to the relative positions of neighboring genes, gene pairs are classified into three patterns: (D) ‘Separation’, no overlapping regions. (E) ‘Overlap’, shared some regions but no one covers the other completely. (F) ‘Inclusion’, one gene covers all regions of the other gene.
