Table 1.

Mean and adjusted line mean (± s.e.) of morphological traits in males of each line. Different letters indicate a significant difference among regimes at p < 0.05 by Student's t-test with the sequential Bonferroni method (SPSS Inc. 2001). Relative line mean is estimated using the least-square mean.
