The distributions of genes and mobile elements are represented as stacked areas. High frequency of genetic recombination (represented by red on a white-red heat scale) is confined to distal regions. In the dot-plot comparison, note how inverted chromosome regions form arcs, indicating that, over the evolutionary time since the divergence of the two species, accumulation of DNA has been greater in more central regions of the chromosomes and elimination of DNA has been more frequent in distal regions. Genes, DNA transposable elements (TEs) and Ty1-copia elements are more frequent in more distal regions. Ty3-gypsy elements are more frequent in pericentromeric regions.
