  1. This table shows the results of testing for overrepresentation of repeat sequences in intergenic regions between convergently transcribed CDSs. For each repeat type, the number of insertions in the two different contexts were tested against the number of intergenic sites containing no short interspersed repeats in the same contexts (bottom row). The displayed P values were calculated from these 2 × 2 contingency tables using a two-tailed Fisher exact test.
