[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.
