  •  QTL Experiment in Brief
    Animals:The F2 population originated from a cross between White Leghorn males and Rhode Island Red females.
     Breeds associated:
    n/a
    Design:Body weight was measured at 239 days of age. Six egg characteristics were measured, including egg weight, shor length of egg, long length of egg, ESS, egg sholl thickness and egg shell weight.
    Analysis:The QTL mapping was determined with the 'Interval Mapping' command of QTX. F2 intercross data were converted into back cross data for analysis of the Z chromosome.
    Software:Map Manager QTX b18 (QTX)
