Genetic variability estimated at 39 autosomal microsatellite loci (STR) and at the KB melanistic deletion on the β-defensin CBD103 gene in the wolf, dog and putative hybrid sampled groups used in this study.

*DIT = Village dogs from Italy; DAP = Apennine dogs; DCZ = German Shepherd dogs from Czech and Slovakian republics; WIT = Wolves from Italy; WCZ = Wolves from Carpathian Mountains; WHR = Wolves from Croatia; WDCZ = Czechoslovakian wolfdogs; HYIT = putative wolf x dog hybrids from Italy.an = sample size.bNa = average number of alleles per STR locus; Np = total number of private STR alleles in each sampled group.cHo = average observed heterozygosity over 39 autosomal STRs.dUHe = average expected heterozygosity (unbiased) over 39 autosomal STRs.eFIS = deviation from Hardy-Weinberg equilibrium (* Pf%LE = proportion of significant correlations (P = 0.05, Bonferroni corrected) among 39×39 pairwise STR comparisons.gPID and PIDsib = Hardy-Weinberg probability-of-identity among unrelated and full sib individuals in the sampled groups, computed using 39 autosomal STRs.hnumber and frequency (in parenthesis) of genotypes at the β-defensin CBD103 gene: K+/K+ = homozygotes wild-type (no deletion); KB/K+ = heterozygotes for the KB melanistic deletion; = KB/KB = homozygotes for the KB melanistic deletion.
