Note.— All alignments shown are human-baboon. We analyzed 9.2 Mb of high-quality alignments of orthologous sequence from human, chimpanzee, and baboon (Liu et al. 2003). Each alignment was cross-referenced with the RepeatMasker output to identify insertions/deletions >100 bases in length that were flanked on both sides by repetitive elements. Such alignments are putative sites of repeat-repeat–mediated deletion. No putative repeat-repeat–mediated insertion or deletion events were detected within 4.9 Mb of chimpanzee-human alignments. A total of nine Alu-Alu–mediated and six L1-L1–mediated recombination events were identified on the basis of the analysis of 4.8 Mb of aligned baboon and human genomic DNA. The type, size, and repeat orientation of the deletions are indicated.
