BW: body weights at 1, 8, 46, 112, and 200 days. GR: growth rates (increase in body weight between consecutive ages). Asym, b2, b3, and xmid: parameters resulting from the nonlinear regression (Gompertz function). PC1–PC4: the first four principal components. The chromosomal locations refer to the location of the significant QTL peaks in the one-dimensional scan (if any). The numbers in parentheses indicate the number of interactions involving each locus, the genomewide significance level being indicated as follows: underlined, <5%; regular type, <10%; italics, <20%). Underlined column headings are the eight loci selected for the second part of the analysis.
