  1. Ne number of effective alleles, He mean value of expected heterozygosity, Ho mean value of observed heterozygosity, 1–2-3MM number of pairs of genotypes out of 12,769 pairs in total (1132) matching at all but 1–2-3 loci, 0MM number of identical pairs of genotypes out of 12,769 pairs in total (1132), PID probability of identity for unrelated individuals, PIDsib probability of identity for siblings, PID-PIDsib/100 number of bears in 100 that could show, by chance, the same multilocus genotype based on PID or PIDsib values. STR marker sets are listed from the least to the most informative on the basis of PID and PIDsib values. Amelogenin gene was not included in the analysis but was included in the individual genotyping, reducing the number of similar genotypes reported in PID-PIDsib/100 columns
