The aim of the diploma thesis was to find out how the frequency of the prion protein genotypes affects the production and reproductive characteristics of sheep in the Czech Republic. We also used graphs to evaluate changes in the frequency of allele of prion protein genotypes from 2003 to present in ten selected breeds of sheep genotyped within the breeding program for scrapie resistance in the Czech Republic. We also dealt with administrative interventions in the genotyping process by the state and recognized breeders' associations. In the next part we evaluated the changes in the frequency of the allele in relation to the development of the sheep properties in the Czech Republic. The results of the research were processed by appropriate mathematical and statistical methods. We have found that the sheep production properties are influenced by the allele frequencies of the prion protein genotypes, and that administrative interventions have contributed to changes in the frequencies of the risk groups in some breeds. Further, we have discovered that most of the highest values of utility properties are associated with the risk group R1.
