Blood type analyses of creole-like cattle: a comparison with Longhorns and mixed controls.

Creole-like cattle blood types were compared with a mixed control group and Longhorn data using hemolytic and electrophoretic techniques. Among the hemolytic tests, the crucial B system analyses indicated that 1) the Creole-like animals were more similar to Longhorns than were the controls; 2) the three groups were different from each other; 3) the three groups were not mutually exclusive. Eleven new phenogroups were postulated. The remaining blood group systems and the electrophoretic tests raised interesting biohistorical questions but were generally less useful in discriminating among the three groups of cattle.
