UCEs in the human genome. The short conserved elements (≥30 bp) are depicted above each chromosome and the UCEs (≥50 bp) are depicted above them. The conservation level of human DNA across primates or placental mammals is shown below each chromosome, where the darker color indicates more conservation. Species in which the human sequences are conserved and selected gene categories are labeled as indicated at the bottom. The selected region for each gene category is magnified for a detailed view in the right panel. R package quantsmooth  and the UCSC custom track  were used for the plot.
