  1. Summary of the results of two-factor ANOVA on (A) dry body weight, (B) locomotor activity and (C) courtship frequency, treating selection regime as the fixed factor crossed with random blocks. Dry body weight was measured in groups of five flies and these values were used as the unit of analysis. For the other two traits, vial means were taken as the unit of analysis. p-values in bold case are statistically significant.
