  •  QTL Experiment in Brief
    Animals:Data for twinning rate from the North American Holstein breed were available through the National Association of Animal Breeders calving ease database.
     Breeds associated:
    Design:Information from granddaughters was used to estimate twinning rate PTA levels of sons. Sires, and sons of sires provided genotypic data.
    Analysis:A total of 268 fluorescently labelled cattle primers were used for microsatellite marker genotyping. A linear regression approach was used for interval mapping through the QTL express program.
    Software:Genescan, Tenotyper, Cri-Map, and QTL express
    Authors:Cobanoglu O, Berger PJ, Kirkpatrick BW.
    Affiliation:Department of Animal Sciences, University of Wisconsin-Madison, Madison, WI53706, USA.
    Title:Genome screen for twinning rate QTL in four North American Holstein families.
