Polymorphism of blood serum post-albumins in Lowland Black-and-White cattle of North-Western Poland.

The authors showed polymorphism of the blood serum post-albumins in a population of Lowland Black-and-White cattle. Having tested 1001 samples of blood serum they found three Poa phenotypes, Poa FF, Poa SS and Poa FS, which were controlled by 2 codominant alleles, Poa(F) and Poa(S). The frequencies of these alleles were: Poa(F)=0.5245 and Poa(S)=0.4755. The contribution of each Poa phenotype in the studied population was: Poa FF=20.88%, Poa SS=25.77% and Poa FS=53.35%. The method used by the authors was based on Geldermann's method (1970) and allows simultaneous determination of the phenotypes of post-albumins and transferrins in cattle blood serum.
