Correlation between nucleotide divergence (or exon's Ka) and ordinal position of introns (A & B) or of exons (C & D) and between intron and flanking exon divergence (or Ka) (E & F). The left panel shows the results from the comparison between human and chimpanzee, and the right panel shows the comparison between two rice lines.
