Integrated GWAS, TWAS, and Functional Enrichment Reveal Candidate Genes for Claw and Hoof Traits in Jiangsu Jersey Cattle

A whole-genome sequencing (WGS) dataset was constructed for 1,595 Jersey cattle. After quality control, variants with imputation accuracy < 0.8 or MAF < 0.05 were removed, retaining 7,102,021 markers across autosomes 1–29.
