Fig. 3From: Estimating the purebred-crossbred genetic correlation of body weight in broiler chickens with pedigree or genomic relationshipsEstimates of additive genetic variance (left) and maternal variance (right) for purebred and crossbred body weight. Traits are body weight measured around 7 (BW7) and 35 days (BW35). Estimates are shown from four models. Error bars represent standard errors reported by the MTG2 softwareBack to article page
