Statistical Analysis
Data from the interrupted matings was analyzed using Fisher exact test on nominal variables (i.e. presence vs. absence). One-way analysis of variance (ANOVA) was used to compare differences in fecundity and on area measures of testes. If significant differences were detected by ANOVA, Scheffe’s post-hoc test was used to determine if the variance was statistically significant between specific samples (e.g.Drosophila strains). All analysis was done using SPSS software.
