Figure 1From: Parallel evolution of conserved non-coding elements that target a common set of developmental regulatory genes from worms to humansThe distribution of CNEs in the C. elegans genome reveals enrichment on chromosome X. Chromosome X contains 884 out of 2,084 wCNEs. This enrichment for wCNEs on chromosome X cannot be explained by either (a) its size or (b) the number of genes it contains compared to the autosomes.Back to article page
