Some Blood Group Antigens in Polish Merino Sheep
This was our introduction to sheep blood group studies. The test sera were not available at the beginning of this study and the experimental material was of unknown composition in respect to blood group antigens.
The reagents were prepared by isoimmunization. In the informal comparison tests arranged by Dr. Rasmusen this year the test sera were identified as reacting with A, B′, C, M, R factors.
The two flocks of Polish Merino sheep were tested by these reagents and their gene frequencies were calculated. No gene equilibrium was found in either flocks and only phenotype frequencies were estimated. The latter were similar in both flock, but it differed considerably in comparison with those for other breeds quoted in the literature.
