CLIC statistics. (a) Different types of CLICs are characterized by the number of species involved. The fraction of opossum-specific CLICs is indicated by light gray. (b) The total number of genes in CLICs from each type. The opossum-specific fraction is indicated as in panel a. (c) Cumulative plots show the fraction of OR genes that is covered by multi-species CLICs of decreasing size (sorted first according to the number of genes in human, and then by the numbers in mouse, rat, dog, and finally opossum). All multi-species CLICs together cover more than 95% of any eutherian OR repertoire (solid black = human, dashed dark gray = mouse, dashed light gray = rat, solid light gray = dog), but only two-thirds of the opossum repertoire (solid dark gray). The coverage of the combined repertoire of all species is shown by black circles. (d) The total number of clusters included in CLICs from each type and size. CLIC, clusters in conservation.
