Figure 7.

Distribution of differential peaks among the sheep genomes. (a) Up-regulated peaks; (b) down-regulated peaks. According to the genome coordinates of detected peaks, peaks can be divided into six categories, including in intergenic region, intron region, promoter region, exon region, 3′ untranslated region (UTR) and 5′ untranslated region. Dots in the bottom denote the peak categories. Black lines connecting the dots show peak numbers shared among several categories. The number above each bar shows the number of peaks for each category or shared category.
