Figure 1.

Comparison of QTL results for body-weight at 56 days of age using the old microsatellite map and an improved map including 434 markers. The black line represents F-values plotted for each cM throughout the genome for the new marker map while the red line displays F-values using the previous microsatellite-based map. The x-axis shows the start and end of each linkage group covered in the new map. Horizontal lines in the graph indicate the 5% genome-wide and the suggestive significance threshold. Black and red vertical bars underneath the x-axis indicate marker positions in the new and old map, respectively. Chromosome 29 denotes linkage group 'E22C19W28E50C23' that has not yet been placed on a chromosome.
