Log Ratio distributions of highly conserved genes. LR distributions from a series of M-CGH experiments comparing two genome-sequenced strains of C. jejuni (NCTC 11168 vs. RM1221). Genes were binned according to PTI and the LR distributions of bins with greater than 95% PTI are presented here. Because the microarray was designed based on strain NCTC 11168, LR deviations from 0 would be the result of sequence divergence or gene absence in strain RM1221. The LR distributions of genes with greater than 99% PTI do not deviate significantly from the average distribution of a Self-self experiment whereas increasingly larger deviations are observed in the range from 98 to 95% PTI.
