As a Chinese local chicken breed, Hongshan chickens have 2 kinds of tail feather phenotypes, normal and taillessness. Our previous studies showed that taillessness was sex-linked dominant trait. Abnormal development the vertebrae could be explained this phenomenon in some breeds. However, number caudal rumpless normal, so rumplessness not related to vertebrae. Afterwards, we found due abnormal rather than In order understand genetic foundation chickens, compared reanalyzed sets data from our studies. By joint analysis genome-wide selection signature association approach, 1 overlapping gene (EDIL3) 16 peak genes (ENSGALG00000051843, ENSGALG00000053498, ENSGALG00000054800, KIF27, PTPRD, ENSGALG00000047579, ENSGALG00000041052, ARHGEF28, CAMK4, SERINC5, ENSGALG00000050776, ERCC8, MCC, ADAMTS19, ENSGALG00000053322, CHRNA8) located on Z chromosome associated with The results study furtherly revealed molecular mechanism trait identified candidate will help improve shape feathers rise individual economic value specific market China.
