Ok guys, from what I understand of genetics, the pigeon has 3 colors, in order of dominance, its Red, Blue, and Brown. Here we identified the genetic basis of the pearl (white) iris color in domestic pigeons (Columba livia) to a nonsense mutation W49X in SLC2A11B via whole genome sequencing and genome-wide association study (GWAS) approaches.
