Подтвержден высокий породоспецифичный потенциал полиморфных локусов g.58335217A&gt;G (ген KDM3A) и g.75953650G&gt;T (ген DBX2) для дифференциации свиней породы дюрок вида Sus scrofa domesticus. Предложена тест-модель для дифференциации особей породы дюрок по биоинформатической оценке совокупного вклада двух SNP генов KDM3A и DBX2. Данная тест-модель не имеет мировых аналогов, а точность ее оценки и специфичности составляет 98,76 и 99,68 % соответственно. С использованием ПЦР-ПДРФ разработан быстрый и простой подход для дифференциации породы дюрок на основании предложенной тест-модели. </p></abstract><trans-abstract xml:lang="en"><p>Genotyping of individuals of 7 commercial breeds of domestic pigs was carried out: Duroc, Landrace, Belarusian Large White, Belarusian Black-and-White, Belarusian meat, Pietrain and Yorkshire for the KDM3A and DBX2 genes. The high breed-specific potential of polymorphic loci g.58335217A&gt;G (KDM3A gene) and g.75953650G&gt;T (DBX2 gene) for differentiation of Duroc pigs of the species Sus scrofa domesticus was confirmed. A test model for differentiation of Duroc individuals by bioinformatic assessment of a total contribution of two SNPs of the KDM3A and DBX2 genes was proposed. This test model has no analogues in the world, and its estimation accuracy and specificity are 98.76 and 99.68 %, respectively. Using PCR-RFLP, a fast and simple approach has been developed to differentiate the Duroc breed based on the proposed test model. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>Sus scrofa domesticus</kwd><kwd>домашняя свинья</kwd><kwd>дюрок</kwd><kwd>однонуклеотидный полиморфизм</kwd><kwd>дифференциация</kwd><kwd>ПЦР-ПДРФ</kwd><kwd>генотипирование in silico</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Sus scrofa domesticus</kwd><kwd>domestic pig</kwd><kwd>Duroc</kwd><kwd>single nucleotide polymorphism</kwd><kwd>differentiation</kwd><kwd>PCR-RFLP</kwd><kwd>in silico genotyping</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Шейко, И.
