Cis-regulatory mutation in the SWS1 opsin regulates its expression. Schematic representation of the promoter of the SWS1 gene in both the F0 of the cross. Sequencing revealed a 691 bp deletion located 751 bp upstream of the translation start site (TSS) of the opsin in A. baenschi (low SWS1 expression) that is absent in the promoter of M. mbenji (high SWS1 expression). The region spanning the deletion comprises a miRNA miR-729 (transcribed on the strand opposite to that of the opsin) and a conserved non-coding element (CNE). Expression of the SWS1 opsin in both the species is denoted by the black arrow located to the right of the gene
