Vi. Glazko et al., STUDYING GENETIC-CHARACTERISTICS OF BROWN CARPATHIAN CATTLE, A VANISHING WESTERN UKRAINIAN LOCAL BREED, Genetika, 32(5), 1996, pp. 668-675
A wide range of variation in immunogenetic and biochemical markers was
found in thoroughbred Brown Carpathian cattle. Comparative analysis o
f genetic structure of Brown Carpathian and Swiss cattle, as well as v
arious hybrids of these two breeds, with respect to polymorphic bioche
mical systems, demonstrated that all hybrids having any gene admixture
of the Brown Carpathian breed formed a single cluster in a dendrogram
and were readily distinguishable from thoroughbred Swiss cattle. Orig
inally, the Swiss breed participated in forming the gene pool of Brown
Carpathian cattle. The selective advantage of some gene associations,
which included the loci of the biochemical genetic systems studied, w
as suggested to be a specific characteristic of the Brown Carpathian b
reed. Genetic differentiation in the groups of hybrids bred in regions
with different ecological conditions (high- and lowland) was revealed
.
