[Immunogenetic similarity and the distance between Swiss brown cattle and 86 other bovine populations].

By using the frequencies of 43-46 antigens of 9-11 genetic blood group systems in 108145 animals the immunogenetic similarity (r +/- m(r)) and the distance (d) between a Swiss brown cattle and other 86 representatives of the Bovinae subfamily were calculated. The position of Swiss brown cattle on a linear model of the Bovinae family was determined. The position has following indexes: r = 0.

[Genetic characteristics of erythrocyte antigens and various polymorphic blood proteins in the Jersey cattle in Moldavia].

The results of the study of immunogenetic structure characteristics of both the purebred Jersey and different generations of the Red-stepp x Jersey, Jersey x Golshtin, Jersey x Golshtin x Red-stepp are presented. We used 47 to 61 reagents and studied 8 types of blood proteins. Some differences in allele frequencies of a number of loci were revealed between the groups studied.

[Genetic aspects of microphylogeny of black-and-white cattle of Uzbekistan].

The genetic aspects of microphylogeny of herds of black and white cattle of Asian and European populations have been studied on the basis of distribution analysis of frequency in 62 antigens of 11 systems of blood groups.
