The percentage refers that the proportion of the physical length of the homoeologous collinear fragment accounts for the whole physical length of the corresponding <i>B. rapa</i> (chromosome_v1.5) or <i>B. oleracea</i> (chromosome_v1.0) chromosome.</p><p>The detailed information of 46 homoeologous collinear fragments of <i>B. rapa</i> and <i>B. oleracea</i> genomes identified in the <i>B. napus</i> genetic map (the source of the data come from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0109910#pone.0109910.s001" target="_blank">Table S1</a>).
