- a, For each cross (top half of the table), the hermaphrodite strain is given first, the male strain last. The mean number of mated hermaphrodites per male, the mean number of offspring per male, the mean number of cross-progeny per male and mated hermaphrodite as well as the mean number of self-progeny per male and mated hermaphrodite are given. SE, standard error. Statistical results (bottom half of the table) are shown for the whole model. If the latter shows at least a trend (P < 0.01), then the statistical importance of different factors in the model are given. In case of a significant interaction factor (cross-progeny per mated hermaphrodite), we also provide the results of Tukey HSD posthoc tests, whereby significantly different groups are indicated by different superscript Captial letters in the top part of the table. The model also included the random factor "experimental date", which did not produced a significant effect (F3 < 1, P > 0.4) except of the analysis of self-progeny per mated hermaphrodites (F3 = 3.03, P = 0.044). Significant probabilities are given in bold.
