Constructing hypothetical chromosomes of the striped catfish, P. hypophthalmus. All scaffolds (> 1 Mb) are anchored to channel catfish chromosomes (n = 29). Blue scaffolds show high similarities to one of the channel catfish chromosomes (round gray rectangles), suggesting an orthologous relationship from a common ancestral chromosome. Red scaffolds anchored to the best-hit chromosome imply less conservation from an ancestral chromosome since more than 50% of genes have hits on other channel catfish chromosomes. Some of their scaffolds might be related to differences in the chromosome number (n = 30 in P. hypophthalmus). Genes related to development and candidate genes for markers are mapped onto striped catfish scaffolds
