Phenotypic characterization. (a) Pigmentation phenotypes of the breeds used to generate the intercross, Light Brown Leghorn (left) showing wild-type color and Fayoumi (right) showing autosomal barring. Photograph credit: Laurence Verrier for the LBL male and David Gourichon for the Fayoumi female. (b) Within-feather pigmentation pattern in chickens. The proposed major Patterning (Pg) locus interacts with several other loci causing complex variation in melanin distribution across individual feathers. Wild-type alleles are indicated by “+.” E/MC1R–Extension/Melanocortin-1 receptor, Ml–Melanotic, Co–Columbian, Db–Dark Brown/SOX10. Modified after Andersson et al. (2020)
