These chromosomal regions are shown schematically on the axes, where major features, including palindromes P4–P8, are indicated. Each dot within the plot represents 100% identity within a 200-bp window. Within the plot, grey shading indicates blocks of uninterrupted sequence alignment. Break points of two inversions (1.5 and 5.0 Mb) are indicated by arrows (green and red, respectively). Supplementary Fig. 1 provides a more highly annotated version of this plot, including gene and pseudogene positions. Cen, centromere.
