Table 2. Filial generation status of wolf-dog hybrids from Estonia and Latvia, estimated with Structure v2.2 under different combinations of ‘Usepopinfo’ parameter settings.

Parameter set – two different ‘Usepopoinfo’ parameter sets (A, B) applied to the same data (n = 103). 0 – ‘Usepopinfo’ set to 0; 1 - ‘Usepopinfo’ set to 1; Ehy – hybrids from Estonia (n = 6); Lhy – hybrids from Latvia (n = 2). The q values (membership coefficient) indicate the probability of individual genotypes to belong to wolf cluster (in parentehesis 90% credible regions).
