| Abstract: | The object of this study was the polymorphism of the ceruplasmin locus in different separate herds of cattle of the Pinzgan and the Red Polish breeds. The investigations carried out corroborated the hypothesis of the triallelic nature of this locus, which expands our knowledge and possibilities in this direction. The frequency of the alleles A, B and C in Red Polish cattle (n = 333) was 0,725; 0,026 and 0,249 respectively, being 0,920; 0,009 and 0,071 in the Pinzgan cattle (n = 369). An assumption is made about the greater value of proteins of a relatively high electrophoretic mobility as compared to those of a relatively low electrophoretic mobility. |
