Comparison of the β-keratin Genomic Regions in the G. gallus and T. guttata Genomes: This figure was constructed using the Artemis program [53] and shows both the positive and negative strands of all genomic loci containing more than three β-keratin genes. Each chromosomal region is annotated above by the three letter species name and the chromosome number. The β-keratin coding regions are colored with the following scheme: scale β-keratin genes = blue, claw β-keratin genes = yellow, feather β-keratin genes = green and feather-like β-keratin genes = magenta. The arrow and strand indicate the directional orientation of each β-keratin gene. Base ranges for each chromosome are listed between the two strands. All labels are based on NCBI BLAST results with cDNA from previous expression studies [8,52,53].
