Comparison of the number of β-keratin coding regions found on each chromosome of both G. gallus and T. guttata. The identification of each probable (Prob.) gene is based on highest similarity to the cDNA nucleotide sequences listed in Table 3. All BLAST hits that failed to meet the stringent standards were determined to be pseudogenes (pseudo) (see Methods for details).
