Fig. 6From: A significant quantitative trait locus on chromosome Z and its impact on egg production traits in seven maternal lines of meat-type chickenFrequency variations of the 29 SNPs associated with higher egg number EBVs. G6, G7, and G8 represent the three generations of the line W2 chickens, and each line represents the differences in the frequency change curve of a SNP’ genotype with higher egg number EBVBack to article page
