Abstract
A whole genome scan was undertaken in a granddaughter design comprisin g 1158 progeny-tested bulls in order to map QTL influencing milk yield and composition. In this paper we report the identification of a locu s on the centromeric end of bovine Chromosome (Chr) 14, with major eff ect on fat and protein percentage as well as milk yield. The genuine n ature of this QTL was verified using the grand(2)-daughter design, tha t is, by tracing the segregating QTL alleles from heterozygous grandsi res to their maternal grandsons and confirming the predicted QTL allel e substitution effect.
