Fig. 1From: X. couchianus and X. hellerii genome models provide genomic variation insight among Xiphophorus speciesFish used in this study. Approximate geographical distributions of three Xiphophorus species. The swordtail, X. hellerii is a male fish showing an extended caudal fin ray, while X. maculatus and X. couchianus are platyfish and do not exhibit this caudal fin extension. The stars are the locations where fishes were collected and the red stars are the location of sequenced fish originally derivedBack to article page
