Enrichment of exons with EG or EE links at the termini of genes. For each gene, all of the core exons were sorted according to their genomic coordinates (from 5' to 3'). The relative position of the i-th exon is calculated as (i - 1)/(n - 1), where n is the total number of exons. The relative positions were partitioned into ten windows. The proportion of exons with relative positions falling in each window was counted for exons with links and exons without links and denoted as p1 or p2, respectively. The y-axis represents the p1/p2 ratio. Error bars represent the 95% confidence intervals of p1/p2. Notice that p1/p2 is higher near the terminal regions.
