Unraveling the Genetic Basis of an Abnormal Gold Feather Phenotype in Auto-Sexing Chickens.

Abstract excerpt

The silver-gold (S/s) sex-linked locus is critically employed in chicken breeding for the auto-sexing of day-old layer chicks. However, the emergence of an abnormal gold feather phenotype, where females lack the characteristic dorsal stripes, leads to frequent misidentification and substantial economic loss. The genetic basis of this abnormality was unknown. To address this, we conducted a genome-wide association...
