Orthologous genes concordantly harbor introns. (A) Schematic example of a pairwise comparison of intron-containing orthologs among three species. (B) The ratios of intron-containing orthologs in a pairwise comparison in contrast to null expectations (solid horizontal colored lines). The binomial confidence intervals (95%) were estimated from these ratios using Bayesian inference with 1,000 iterations (vertical colored lines). Dotted circles denote introns may be retained in genes by chance (χ² tests, P > 0.01).
