A novel codominant plumage color pattern of white breast patches in WugangTong geese was controlled by EDNRB2.

ABSTRACT: Two basic plumage color patterns are observed in adult geese: solid grey (G) or colorless white (W). However, a Chinese indigenous breed, the Wugangtong goose (WGT), continues to be subject to selective breeding efforts as it displays segregation of plumage colors, including G, W, and a novel color pattern designated Wb (G with white breast circles). The underlying genetic mechanisms responsible for the Wb phenotype are yet to be determined. The current study employed the population differentiation index (F_ST) to analyze 90 geese exhibiting diverse plumage colors, identifying the fifth intron of EDNRB2 as a particularly noteworthy region with the highest F_ST values. Sanger sequencing of the region surrounding the EDNRB2 gene identified a 14-bp insertion within exon 3
