Figure 2From: Sequence analyses of the distal-less homeoboxgene family in East African cichlid fishes reveal signatures of positive selectionSecondary structure and positively selected sites for four partially sequenced Astatotilapia burtoni Dlx proteins. Secondary structure predictions were obtained from the PSIPRED server (http://bioinf.cs.ucl.ac.uk/psipred/). Positively selected sites identified by the site model analyses (CodeML) and the SLR analyses are highlighted in red (BEB and/or SLR) or orange (NEB) boxes. (A) Dlx1a. (B) Dlx2a. (C) Dlx3a. (D) Dlx4b.Back to article page
