Foot-feathered birds share a 17-kb deletion upstream H2AFY. (a) Total number of samples without deletion (wild type), heterozygous or homozygous for the deletion. (b) Genome-wide depth of coverage of chromosome 13 (16.0–16.2 Mb) for a Breda fowl (little feather development) individual and the wild Gallus gallus (scale epidermis). The deletion (13:16,089,992–16,107,660) is visible in the foot-feathered sample by the absence of coverage. (c) Location of deletion (highlighted in gray), lncRNA, H2AFY, and QTL (QTL127125) along the 57-kb significant region on chromosome 13.
