Spatial genetic structure and predicted inbreeding depression. (A) Correlogram for the kinship coefficient among pairs of Rhododendron brachycarpum individuals, expressed for nine distance classes (values on the x-axis represent the upper limit of each distance class). Dashed lines represent the 95 % confidence interval for the null hypothesis that assumes no genetic structure based on 9999 randomizations. Asterisks indicate significance (P < 0·05) for each distance class. (B) Predicted inbreeding depression as a function of the spatial genetic structure for stages.
