Heritability of the trait body weight in salmon of wild, hybrid and farmed origin.

Heritability h2 of the trait body weight (log) calculated using the animal model, implemented by MCMCglmm. The upper and lower 95% highest posterior density HPD intervals represents the credibility intervals of the estimated h2. Models were fitted separately for each experimental group, in both treatments. In addition to the breeding value, Animal, the random effect of tank was included when this improved the fit of the MCMCglmm. Model selection was performed by the use of the Deviance Information Criterion (for DIC comparisons see Table S3).
