[i] The total number of rearrangements and the total number of interchromosomal rearrangements on the edges of the evolutionary tree between the human, mouse, rat, and chicken genomes (see top of Fig. 2) are shown for both gene-based and sequence-based data at various thresholds. MA is the mammalian ancestor and RA is the rodent ancestor. The numbers are normalized using the MA–human edge to simplify comparison.
