Figure 3

Graph showing proportions of conservation statuses of exons in human and mouse genome. Human exons were categorized according to conservation status of mouse homologous exons. A non-conserved exon is a human exon that does not align with a mouse genomic region using a threshold of 70% for coverage and 60% for identity. A genome-conserved exon is a human exon whose alignment with a mouse genomic region exceeds the above thresholds. A transcript-conserved exon is a human exon whose alignment with a mouse transcript exceeds the threshold [51]. Numbers shown at "Flanked by SNPs" and "All" in each category on the horizontal axis are numbers of genomic regions of sdSNPs (Process 7 in Figure 2) and of all exons in the human genome (Panel A of Table 1 in [51]).
