Identity index histogram. A histogram of the identity index for each gene in the data set COL versus N315. The identity index tend to be either very close to 0 or 1. The marked threshold at 0.7 is used to separate divergent from present genes unless otherwise stated. The histograms for the other three data sets are very similar, see [16].
