Examples are given for some traits and show the results gained by including several genome-wide significant QTL across chromosomes a multiple position models were included together with the same environmental independent variables as in the initial model; b trait acronym, for definition see Table 2; c each QTL position was analyzed separately for trait association; F ratio: mean square estimates of the additive and dominant components in relation to the error variance of the model; VF2: proportion of error variance reduction by inclusion of additive and dominant components in the initial model; r2: determination coefficient; d QTL positions analyzed in combination |
