  •  QTL Experiment in Brief
    Animals:Six large paternal half-sib families with a total of 285 sons of the commercial Norwegian Cattle population were used.
     Breeds associated:
    Design:First-parity twinning rexords of approximately 239,600 cows were used in the study. All cows were daughters of 285 bulls belonging to six paternal half-sib families previously used to construct a male genetic map in Norwegian Cattle Population.
    Analysis:The statistical analysis followed the multiple marker regression method, but incorporated a random effect of son in the model.
