  1. *Average of 10 replicates. t1000, t500, t100 and t20 = proportion of the variance accounted for the markers (varM) explained by those with the largest 1000, 500, 100 and 20 absolute effects, respectively. var M= ∑ j g ^ i 2 2 p i 1 − p i , in which g ^ i and pi are the estimated effect and the allele frequency for the ith marker, respectively. |g| > 0 = number of markers with non-null estimated effect. kurt = excess kurtosis of the distribution of estimated marker effects. Trait = weight at 6 weeks (W6W), weight growth slope (WGS), body length (BL), percentage of CD8+ cells (%CD8+), ratio between CD4+ and CD8+ cells (CD4+/CD8+).
