  •  QTL Experiment in Brief
    Animals:Animals were Dorset and Dorset x East Friesian ewes.
     Breeds associated:
    Design:Animals were genotyped for two SNPs in MTNR1A and analyzed for age at first lambing and days between first and second lambing.
    Analysis:The general linear model procedure was used.
    Software:SAS
