  •  QTL Experiment in Brief
    Animals:Animals were Baluchi ewes.
     Breeds associated:
    Design:Animals were genotyped using the Illumina OvineSNP50 BeadChip and GWAS was performed for litter size. A total of 45,342 SNPs were used for analysis.
    Analysis:The general linear model was used for GWAS.
    Software:GenABEL in R, AIREMLF90, BLUPF90
