The distribution of observed/expected CpG dinucleotide ratios among predicted D. Noxia transcripts. CpG(O/E) distributions of all predicted transcripts were determined according to the equation CpG(O/E) = CpG frequency / [C frequency x G frequency]. The CpG(O/E) distribution of D. Noxia is bimodal. Y = number of sequences per category, X = CpG(O/E) ratio category (0.05 per category).
