Figure 6

Possible scenarios for the creation of bidirectional promoters. Scenario A shows original gene pair being duplicated into a series of paralogous gene-pairs, where respective homology is maintained for all genes, while scenario B shows independent acquisition of gene partners via either a recombination event or de novo transcription.
