THE EFFECT OF ALLELES INTRODUCTION ON THE STATUS OF ALLELE POOL OF BLOOD GROUP SYSTEMS LOCI IN THE POPULATION OF DIMINUTIVE PIGS IN SB RAS ICB

The paper shows the part played by the introduction of blood group systems alleles as the factor of formation of allele pool of immune genetic markers in SB RAS ICG diminutive pig population. (further DMP) The DMP blood added to the blood of Landrace (1998) and Vietnamese boars (2005, 2010) made the DMP herd have the alleles, such as E^edf, L^adhjl and L^agim. It was the introduction of the alleles from Landrace and Vietnamese boars rather than convergation processes that made the crucial contribution to the phylogenetic mapping of the modern DMP population, that being well-reasoned and testified to. Based on the allele presence/absence, two major components were spaciously plotted in the map through Euclidean distances. The components show DMP clusterized with the pig breeds and populations which were used in their production. Given the grouping happened based on the 2013 data about the presence or absence of blood group systems alleles, the modern DMPs are found in the same cluster with Svetlogorsky mini-boars, minisibs and Vietnamese breed. Given the clusterization resting upon the alleles detected in the population founders, DMPs are found in the same cluster with Svetlogorsky founding boars. In addition, the paper shows the contribution of each of the initial forms to the gene pool of the modern DMP population as well as the contribution of each of its founders. Over a half of the blood portion belongs to the Svetlogorsky founding boars, but the contribution of each of the rest of the predecessors constitutes nearly 0.1–0.2.
