Table 3.

Natal dispersal influences the likelihood of inbreeding (coded as ‘0’/‘1’, and equivalent to ‘1’ whenever f≥0.03125) in males and females. (GLM with binomial error distribution and logit link. Parents from parent–offspring matings are excluded from the analysis, and only one randomly chosen sibling from brother–sister pairs is included when both sexes are analysed together. Variance explained by the model: 10.8%.)
