Figure 2. Genomic and phylogenetic analysis of chicken IRBP
A: Genomic structure of chicken IRBP compared to human  and zebrafish  IRBP; exons are represented by boxes and introns are represented by lines. B: Phylogenetic analysis of vertebrate IRBP modules. Unrooted, neighbor-joining tree was prepared in Biology Workbench using amino acid sequence alignments and default parameters for PHYLIP [53,79].
