Table 2. Intrasite nucleotide differences for the mitochondrial rRNA genes, 12S and 16S, among individuals of Cryptocercuscollected for this study. Listed are: collection location, lengths of amplified and sequenced fragments, mean number of nucleotides, and the percent of bases differing in pairwise comparisons of individuals within collection locations with multiple specimens (± standard error). Kambhampati et al. (1996) reported that they did not detect any intrasite sequence variation.
