Harming ability of the selection regime males. Mean fitness (progeny production) of LH-females under the experimental conditions: after an exposure to the selection line males for one hour (single mating, SM) and two days (continuously exposure, CE). Total number of progeny produced by all the females in a vial was counted and a mean is calculated using this data. The vial means were then used as the unit of analysis. Points not sharing common letters are significantly different (determined using Tukey’s HSD).
