Figure 1From: Predicting heterosis for egg production traits in crossbred offspring of individual White Leghorn sires using genome-wide SNP data Predicted heterosis in egg number and egg weight for the 3427 sires studied. On the x axis, the sires are numbered from 1 to 3427 and the y axis shows predicted heterosis (left: egg number; right: egg weight (g)). Each point on the graph represents the average heterosis in the offspring of a particular sire; each sire was mated to one dam-line, but to several hens from that line. Colours represent the 16 crosses in this study.Back to article page
