Fixed effects terms from the linear and generalized linear mixed models. Significance of the terms was determined by comparing nested models using chi-squared likelihood ratio tests. Bold values are significant at P ≤ 0.05. Non-significant terms were removed from the final model. The direction of the modeled relationship between each term and the trait of interest is given by (+) and (−) signs. Parameters that were not significant in the model are denoted by n.s.
