The Genomic Organization of the β-keratin Subfamilies of Gallus gallus domesticus: Reproduction of the ~100 kb region containing the β-keratin gene cluster of Gallus gallus domesticus from Presland et al [12]. Arrows indicate the transcriptional orientation of the coding regions, where known. The boxes represent coding regions of unknown transcriptional orientation. The three β-keratin subfamilies (feather-like, feather, and claw) are labeled.
