Genomewide likelihood ratio profile plot. The profiles of the log-likelihood ratios (LR) between the full and reduced (no QTL) model estimated from the functional imprinting model for body mass growth trajectories across chromosome 1 to 19 using the linkage map constructed from microsatellite markers . The threshold value for claiming the existence of QTLs is given as the horizonal dotted line for the genome-wide level and dashed line for the chromosome-wide level. The genomic positions above the threshold line and corresponding to the peaks of the curves are the MLEs of the QTL positions. The positions of markers on the linkage groups  are indicated at ticks.
