[Interlocus associations of various genetic biochemical systems in cattle]

Variation of some genetic biochemical systems (transferrin, ceruloplasmin, amylase-I, and kappa-casein) were studied in five cattle groups of different origin. Data on linkage disequilibrium demonstrated that some syntenic genes did not exhibit interlocus association. Conversely, interlocus association appeared between some loci that were located in different chromosomes. Apparently, the patterns of these associations may be specific for gene pools of individual groups from the same animal species.
