  1. QTLs were detected coming from ‘Old Home’ (OH) and ‘Louise Bonne de Jersey’ (LBJ). Percentage of the phenotypic variance explained by each QTL (% Expl.) was calculated using ANOVA. See Table 1 for an explanation of the variables. LOD score indicates the genome-wide significance of the QTL a: 90 %, b: 95 % and c: 99 %
