¹Body weight was recorded on each animal at approximately 7 (Weight2), 9 (Weight3) and 12 (Weight4) months post-hatching.

²Family-based association analysis was performed with program PLINK version 1.07 [22]. Here, t is the t-statistic for regression of phenotype on allele count (by.x), P is the asymptotic P-value for t-statistic, and the empirical P-value was estimated using 20,000 permutations.

^**indicates significance at P<0.01.

^*indicates significance at P<0.05.
