Genome-wide variation dataset of Wenchang chickens generated from whole-genome resequencing

This dataset contains genome-wide variant data identified from whole-genome resequencing of 361 Wenchang chickens (Gallus gallus domesticus) for genome-wide association analysis of egg-production traits. The samples were collected from a Wenchang chicken population in Hainan Province, China. Whole-genome resequencing was performed using the DNBSEQ platform with paired-end reads, and the resulting sequencing data were analyzed to identify genome-wide genetic variants. These variants were used to investigate the genetic basis underlying egg-production traits, including average egg weight, age at first egg, total egg number at 43 and 56 weeks of age, average clutch size, and maximum clutch size.
