The quality of milk in cattle is influenced by many genes. One of them is gene CSN2. The aim of this diploma thesis was to test animal population of about 240 individuals of Jersey and Brown Swiss breed in Czech Republic. DNA was isolated from blood. Genotypes were determined by sequencing followed by determining genotypes and alleles frequencies. The association analysis of single nucleotide polymorphism with milk yield parameters was performed by using SAS program. The selected parameters were lactation days, milk yield (kg), fat content in milk (% and kg) and protein content (% and kg). These parameters were available for 126 animals. Statistically significant effect of CSN2 genotype on the selected milk production traits was not found in the studied population. Only effect of breed was found as statistically significant.
