The study of the genetic markers and identifying new markers involves an increasing number of research projects in the fields of genetics of immunology, biochemical genetics, molecular genetics, quantity genetics and the genetic improvement of animals.Having considered the importance of genetic polymorphism of biochemical structures we considered a study of the genetic characterization of a sample in a cattle population, based on the information offered by the genetic polymorphism at hemoglobin and transferrine loci and the analysis of the serum. Two phenotypic category, hemoglobin A (79,4%) and AB (20,6%), has been identified for hemoglobin locus. Five categories of individuals, homozygous for TfA/TfA (2.9%), TfD/TfD (58,8%) and heterozygous for TfA/TfD (20.6%), TfA/TfE (5,9%), TfD/TfE (11,8%) have been identified on seric transferine loci; determined of existence of interest locus for three kinds of genes TfA, TfD and TfE with codominant effect. Blood factors were described in order to use them as genetic markers with the purpose of determine the homogenity or heterogenity degree for two cattle population.Serologic relations were observed between the factors of B system. The most relevant was the complex BGK. These tree factors were observed in five different combinations, namely BGK, BG, B, G, and their total absence.
