Distribution of the percentage of phenotypic variance explained by the QTL regions identified using different SNP densities for the LW-line. Distribution of the percentage of phenotypic variance explained by the QTL regions identified for the LW-line using a 80 K, b 660 K and c iWGS genotype scores, d iWGS dosage scores. The percentage of phenotypic variance explained was calculated as follows: \(\frac{{2p_{i} \left( {1 - p_{i} } \right)*\hat{b}^{2} }}{{var\left( {phenotype} \right)}}*100\), where the phenotypic variance was 1.08
