DNA-based molecular markers have a very high polymorphism level, and they have been successfully used for evaluation of genetic diversity and variation in breeding programmes with an impact on the level of genetic conservation schemes. The aim of the presented study was to provide information on the genetic structure in the Pinzgau cattle in Slovakia, based on polymorphism of 61 monovalent sera. The genetic distance was computed for all possible combinations between 777 animals. The obtained genetic distances were pooled according to trie relationship coefficient. The average genetic distance decreased from 0.225 (in the group with Rxy between 0 and 0.125) to 0.147 (the group with Rxy between 0.375 and 0.5). The distribution of the genetic distance formed specific distribution curve. The average value of the genetic distance could be used to analyse small population with no pedigree information.
