a: The expected number of repeat elements was calculated by dividing the total number of repeat elements in the human and chimpanzee genomes by the length in bp of the respective genomes (as summarized in Supplementary Table 7) and multiplying by the length of the inversion-flanking regions analysed (in bp).

b: as determined by the test for observed versus expected rates of occurrence of repeats based on the Poisson distribution.

MIR: mammalian-wide interspersed repeats; LTR: Long Terminal Repeat retrotransposons
