Abstract

The concept of «partblood» most are based on assumptions about longing action of genes that control is taken part in polygenic traits productivity and their system of uniform distribution of landed offspring. The literature describes few actual studies of genetic processes that occur in the offspring of crosses purebred animals. In this regard, the task of our study included a comparative analysis of the genetic structure of the source rocks (symentaly, grizzled red–Holstein) and their offspring landed the «share of blood» 1/2 (F1) and 3/4 (F2). Analysis of the genetic structure of all four groups of animals by polymorphic genetic and biochemical systems showed that transferrin locus for the particular animals are different from parental forms. So a group of animals with 1/2 blood (F1) display of high frequency of allelic variant Tf D2 (0,646). According to AM–1 locus in the studied groups manifestation of the highest frequency in the group of animals 1/2 halfblood (F–1) – 0.712 and this group is just as close to a group of purebred symentaliv (0.806). For purynnukleotydfosforylazy locus was found a high frequency of phenotypes at high activity in a group of purebred symentaliv (NP–H – 0,25). Cluster analysis showed that for genetic and biochemical systems group symentaliv (bedrock) form one cluster, and the Local animals (F–1 i F–2), and a group of red Holstein (parent rock) differs from them with a group black and other forms black Holstein, an independent cluster.
