Comparative genomics analysis for the genetic map of S.argus. (a) the numbers of markers per linkage group that showed homology with genome sequences of other fish, listed on the x-axis; (b)-(d) Oxford grids showing conservation of macrosynteny relationships between S.argus linkage groups and chromosomes of L. crocea (b), O. niloticus (c), and P. olivaceus (d). The numbers of S.argus ddRAD markers with significant BLASTn hits in the other fish are presented in box, and the putative syntenic pairs are indicated by gray boxes along the diagonal. (e) Circos diagram representing syntenic relationships between proposed linkage groups of S.argus (right) and published chromosomes of L. crocea (left). only markers on each linkage group of S.argus that were mapped to a single chromosome of L. crocea were illustrated. Each colored arc represents a marker match between linkage group and chromosome
