The comparison of two strains is found at the intersection of the row and column corresponding to the respective strains. Strains are compared based on the number of genes shared between the pair, the number of genes found in one strain but not the other, and the number of shared genes that are unique to that pair of strains. A typical pair of strains differs by 395 genes. Similar pairs of strains are shaded in yellow, while divergent strains are shaded orange.<p><b>Copyright information:</b></p><p>Taken from "Characterization and modeling of the core and supragenomes based on the complete genomic sequences of Rd and 12 clinical nontypeable strains"</p><p>http://genomebiology.com/2007/8/6/R103</p><p>Genome Biology 2007;8(6):R103-R103.</p><p>Published online 5 Jun 2007</p><p>PMCID:PMC2394751.</p><p></p
