Phylogenetic footprinting of the SWS1 promoter in teleosts. a VISTA alignment of the SWS1 promoter region from tilapia, stickleback, medaka and zebrafish relative to M. zebra (X-axis) show that both the miR-729 and CNE are conserved among teleosts. Grey peaks indicate more than 50% conservation in a 50 bp sliding windows; the arrow at the bottom indicates the start site of SWS1 gene. Horizontal grey bar below the X-axis shows the location of the putative deletion in a few species from Lake Malawi. b VISTA comparison of the same region between M. zebra and zebrafish. Grey peaks indicate more than 25% sequence conservation in 50 bp sliding windows. Both the miR-729 and CNE are marked by black bars below the horizontal axis
