Fig. 2

Scatter plot of RS of species with rare arrangements (Single rearrangement and Double rearrangements). The red dotted line represents the average RS of 47 species with rare arrangements; The black dotted lines indicate RS of species belonging to four major patterns (global arrangement). The figure also shows the species with the highest and the lowest RS and their rearrangement information, and the names of genes with two changed flanking genes are marked in red, the names of genes with changes of one-sided gene are marked in purple
