TABLE 2.

A posteriori contrasts of significant explanatory variables for reproductive traits of (a) males and (b) females. Contrasts with Bonferroni corrections were performed to interpret which conditions significantly differed from each other. ‘Temperature’, average temperature in each treatment (25°C, 27°C and 29°C; here represented as ‘25’, ‘27’ and ‘29’, respectively); ‘line status’, DGRP line classification based on male fertility performance (low or high lines; here represented as ‘Low’ and ‘High’, respectively; Zwoinska et al., 2020). Test statistics reported: z‐ratios for binary variables and t‐ratios for productivity. Statistically significant contrasts are represented in bold, statistically marginally significant contrasts are represented with *
