TABLE 1.

Generalized linear and linear mixed‐effect model output for reproductive traits of (a) males and (b) females. df indicates the degrees of freedom. χ ² provides the chi‐square value obtained in each analysis. ‘temperature’, temperature in each treatment (25°C, 27°C or 29°C); ‘line status’, DGRP line classification based on male fertility performance (low or high lines); ‘block’, week in which the data were collected (1 or 2). Statistically significant effects are represented in bold, statistically marginally significant effects represented with *
