Figure 3.
Comparison of gene order between zebrafish and Tetraodon. (A) Comparison of the chromosomal locations of 28 orthologous gene pairs on zebrafish (Danio rerio, or Dre) LG 16 with Tetraodon nigroviridis (Tni) chromosome 8. (B) Comparisons of the chromosomal locations of 38 orthologous gene pairs on Dre LG 2 with Tni chromosome 15. Lines between the compared chromosomes connect positions of orthologous gene pairs in the two species. Distances between markers on a single chromosome are shown to scale, but compared chromosomes have been scaled to equivalent lengths. Map positions for zebrafish genes were derived from this work, and those of Tetraodon were obtained from http://www.ensembl.org/Tetraodon_nigroviridis/. Seven of the 35 gene pairs between Dre16/Tni8 shown in Figure 2B are not shown here, because the precise locations of these seven genes along this Tetraodon chromosome have not yet been reported.
