Number of dogs tested, average sample size per locus, inbreeding coefficient (FIS), expected and observed heterozygosity (HE and HO; SD, standard deviation), and allelic richness corrected for sample size (mean number of alleles per locus when 14 individuals – the sample size for miniature schnauzer; sampled with replacement). Significance refers to the difference between HE and HO, *p < 0.05; **p < 0.01; ***p < 0.001.

1 Medium sized poodles, miniature poodles and toy poodles

2 Medium sized poodles with brown or black coat-color

3 Miniature poodles and toy poodles with brown or black coat-color

4 Medium sized poodles, miniature poodles and toy poodles with silver (grey) or white coat-color

5 Medium sized poodles, miniature poodles and toy poodles with apricot coat-color

6 Without size correction
