Fig. 4From: A significant quantitative trait locus on chromosome Z and its impact on egg production traits in seven maternal lines of meat-type chickenLD plots of the 29 significant SNPs from 3159 chickens in line W2. Box plots were structured using four SNPs selected from four blocks. The SNPs effect was tested using Kruskal-Wallis univariate ANOVA analyses for egg number EBVBack to article page
