The aim of the study was to assess the biodiversity of farmed fur animals from the Canidae family (common fox, polar fox, and raccoon dog) using nuclear and mitochondrial markers. The study involved 434 animals. The biological material included whole peripheral blood or skin tissue. The isolated genetic material was subjected to qualitative and quantitative analyses. Mitochondrial DNA (mtDNA) gene fragments (COX1, COX2, CYTB) and nuclear DNA (nDNA) gene fragments (MSTN1, MSTN2, MSTN3, IGF1, GHR) were amplified with the PCR (polymerase chain reaction) technique. The amplicons obtained were sequenced or subjected to PCR-RFLP (restriction fragment length polymorphism) reaction, and bioinformatics analyses were performed. The interspecific analysis of the nDNA sequences revealed a total of 25 polymorphisms. On the other hand, the interspecific analysis of the mtDNA gene fragments identified 277 polymorphisms. The COX1 gene fragment exhibited the greatest variability. It was shown that the frequency of polymorphisms within the mitochondrial genome was almost 20-fold higher than that in the nuclear genome of the raccoon dog. It was found that the genetic distances revealed by the analysis of the mitochondrial gene fragments were similar to the results obtained by the nDNA analysis. The genetic distance between the raccoon and common fox was the greatest. The smallest phylogenetic distance was revealed between the two fox species. The study results indicate mitochondrial and nuclear genes may be alternatively used for determining the phylogenetic relationships between fur animals from the Canidae family.
