  •  QTL Experiment in Brief
    Animals:Chickens were from two elite breeding lines of egg-laying chickens: Line 1 (white egg) and Line 2 (brown egg).
     Breeds associated:
    n/a
    Design:Birds were genotyped for about 3000 SNPs using an Illumina array and analyzed for egg quality and production traits.
    Analysis:SNP-wise and genome-wise analyses were conducted, using mixed model analysis and BayesB analysis, respectively.
    Software:SAS, ASReml
