Distribution of segmental duplications (≥90% and ≥10 kb) in the rat genome. The pattern of (A) interchromosomal duplications (red) and (B) intrachromosomal duplications (blue) are depicted for all duplications ≥90% sequence identity and ≥10 kb in length. For clarity, interchromosomal distribution patterns with the random, unassigned sequence contigs (chrUn) are not shown for (A). For more detail, including % identity and pairwise relationships of all duplications and alignments, see http://ratparalogy.cwru.edu.
