Opis:: Analysis of genetic relatedness and inbreeding in Polish population of the Newfoundland dog breed. The aim of the study was to analyse the fi ve-generation pedigrees of Newfoundland dogs, registered in the Polish Kennel Club and shown in 2015 in Poland. Pedigrees come from the Polish Newfoundland Club website and their analysis was possible with the use of the international pedigree database (https:// www.newfoundlanddog-database.net/). Inbreeding coeffi cient (COI) and ancestor loss coeffi cient (AVK) were calculated and pedigrees were analysed for the presence of common ancestor. Results indicate low mean COI values, with individual values ranging from 0.78% to 7.03%. The mean kinship was 3.14. Five-generation pedigree analysis did not show high inbreeding in the population studied and AVK exceeded the suggested value of 85% only in one case. It can be thus concluded that the population of Polish Newfoundlands, at least its part, presented at shows in 2015 and most likely intended for breeding, is not to be considered inbred.

Opis:: Genetic diversity of native Japanese dog breeds in the primitive type. In the following paper the genetic distance among selected Japanese dog breeds (Akita, Kishu, Kai, Shiba, Shikoku, Hokkaido) was estimated. In order to determine genetic differentiation we analyzed a fragment of the mitochondrial control region and 10 microsatellite loci. We found that variation of the nuclear DNA was larger than that at the level of mitochondrial DNA. Within a fragment of 614 bp of control region, 13 haplotypes were identifi ed. The highest diversity of mitochondrial DNA was found in Akita. Based on mitochondrial DNA analysis, genetic distance between breeds ranged from 0.003 to 0.018. The lowest genetic distance was observed between Shikoku and Kai (0.003), and the highest between Shiba and Akita (0.018). After the analysis of nuclear DNA, 65 alleles were identifi ed. The mean percentage of polymorphic alleles in the applied microsatellite markers was 94.4% ±2.5%. The analysis showed that, the highest distance estimated on the frequency of microsatellite markers was found between Kai and Hokkaido (1.066), and the lowest between Shiba and Kai (0.212). Hokkaido and Shikoku were the only clearly distinguishing breeds.
