  1. A: summary of results from a three-factor mixed model ANOVA on the females mean longevity using selection (FCB and FSB) and treatment (cold shock and no shock) as fixed factors crossed with the random block (1–5). B: summary of results from a three-factor mixed model ANOVA on the males mean longevity 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
