  1. A: summary of results from a four-factor mixed model ANOVA on the egg viability using selection (FCB and FSB), treatment (cold shock and no shock), and period (0–6 h and 24–30 h) as fixed factors crossed with the random block (1–5). B: summary of results from a three-factor mixed model ANOVA on the number of mating pairs (mating frequency) using selection (FCB and FSB), and treatment (cold shock and no shock) as fixed factors crossed with the random block (1–5)
  2. p-values in bold are statistically significant
