Abbreviated history of violet-blue–sensitive (SWS2) genes in teleost fishes. The SWS2 gene was present in a single copy before the neo-teleostei gene duplication, which gave rise to SWS2A (light blue) and SWS2B paralogs (dark blue). In the percomorpha lineage, a subsequent duplication event gave rise to SWS2Aα and SWS2β paralogs. Although these three paralogs have been retained in many species, one or more paralogs have been lost in percomorph fishes. The syntenic relationship is shown to illustrate that these were tandem duplications occurring on the same chromosome, with example species listed below in parentheses. Modified from ref. .
