The GWAS summaries of 21 agronomic traits in Simmental cattle

The genotyped with Illumina Bovine 770K Bead chip were imputed to sequence level using Beagle 5.4 based on a multiple-breed reference population consisted of 1,847 individuals from run 8 of the 1000 Bull Genomes Project. A total of 8.2 million SNPs (MAF > 5% and missing rate < 10%) for 854 ~2,622 individuals were used to perform the genome-wide association analysis. Before running the GWAS, the phenotype were adjusted for year, sex, age (month), and the first two principal components produced by PLINK and normalized by rank-transformation separately using the transform function included in the GenABEL. The associations among SNPs and traits were tested using mixed linear models in GCTA software.
