[Genetic structure of local Ukrainian cattle breeds].

Analysis of 6 cattle breeds (5 local Ukrainian breeds and the Holstain breed) on the 9 polymorphous molecular-genetic markers (transferrin, ceruloplasmin, amylase-1, posttransferrin, receptor to vitamin D, haemoglobin, leptin, kapa-casein) was carried out. The rare allele of transferrin was revealed in two local breeds and the rare allele of leptin--in two another local breeds. Associations between syntenic loci (transferrin, ceruloplasmin, kappa-casein, receptor to vitamin D) were observed only in the local breeds but not in the Holstain one. Locus-specific conservation of the ancestor allelic variants in the local breeds and effect of selection on interloci associations are discussed.
