  •  QTL Experiment in Brief
    Animals:Animals were Wadi ewes.
     Breeds associated:
    n/a
    Design:Animals were gentoyped using the Ovine Infinium HD SNP BeadChip and analyzed for SNP association with supernumerary teats. A total of 509,454 SNPs were used for analysis.
    Analysis:Genome-wide association analysis was conducted based on a case-control model.
    Software:PLINK, Haploview, GenABEL in R, GENEPOP
