The GWAS applied Bayes C method and weighted single step GBLUP considering (SI) or ignoring (SII) phenotypes from non-genotyped animals, under different weights (w1, w2 and w3) for the SNPs. 1Ch = chromosome; Wi = 1 Mb window within the chromosome; pvar = proportion of variance explained by the SNPs within the window. The most common windows (ranked as top 10 in at list four analysis) are highlighted in bold.
