  1. Significant values of FIS are indicated with *p-value < 0.05; **p-value < 0.01; ***p-value < 0.001.
  2. N the number of individuals in the size classes, Na the mean number of alleles, Ho the observed heterozygosity, He the expected heterozygosity, FIS the inbreeding coefficient, FST values of pairwise comparisons between size classes and Prxy the percentage of individuals sharing at least one common parent (i.e. percentage of relations with rxy > 0.25) within the two size groups and considering the two size groups mixed (in bold).
