Summary Studies were carried out on the polymorphism of alkaline ribonuclease in Black‐and‐White cattle in the north‐eastern region of Poland. Leucocytes isolated from peripheral blood were used. Three phenotypes were defined, consisting of the combination of two alleles. The gene frequency was: q 4 = 0,7082, q B = 0,2918. In calves the frequency of allele RNA‐ase B and number of RNA‐ase A / RNA ‐ase B heterozygotes were higher than in adult animals.
