For each trait we performed a QTL scan, in which the following LMM is fit at loci spanning the genome: where is the normal quantile for trait j for individual i , is the intercept, locus m [ i ] is the effects of genetic locus m on individual i , batch[ i ] and sex[ i ] are the contributions of batch and sex on individual i , fit as fixed effect covariates, kinship chr[ m ], i and i are random terms representing a polygenic effect that can account for population structure and unstructured error, respectively: kinship chr[ m ], i N( 0 , G m 2 ) and i N(0, 2 )
