FIGURE 1.

Phenotypic variation of reproductive traits in males and females exposed to three different temperatures during development. Flies developed at 25°C, 27°C or 29°C. In each of the 40 DGRP lines, we measured (a) the proportion of vials in which mating was observed within the first 8 hr (i.e. mating success), (b and c) the proportion of vials in which at least one larva emerged from eggs (i.e. fertility) and (d and e) the number of adult offspring (i.e. productivity) per vial. Colour tones represent different line status (‘high lines’, dark grey, ‘low lines’ light grey), each dot represents an individual line (±SE). (a, b and d) show the average trait values when DGRP males were exposed to the different temperatures; (c and e) show the average trait values when DGRP females were exposed to the different temperatures
