  •  QTL Experiment in Brief
    Animals:Birds were Rhode Island Red and White Leghorn chickens.
     Breeds associated:
    Design:Birds were subjected to whole-genome sequencing, and GWAS was performed for age at first egg. A total of 4,717,481 (White Leghorn) or 4,882,037 SNPs (Rhode Island Red) were used for GWAS.
    Analysis:The general linear model was used for GWAS.
    Software:SAMtools v1.16.1, Picard tools v2.25.2, PLINK, TASSEL
