2003 Poultry Science 82:1215–1222 An error occurred in the transfer of data from our database to the QTL software. This had a serious effect on the results of the half-sib and the line-cross analysis as published. Here we present the corrected QTL results obtained using the QTL express program, available through a web interface (http://qtl.cap.ed.ac.uk/) (Seaton, G., C. S. Haley, S. A. Knott, M. Kearsey, and P. M. Visscher. 2002. QTL Express: Mapping quantitative trait loci in simple and complex pedigrees. Bioinformatics 18:339–340).
