The intrabreed genotype heterogeneity in Ukrainian beef cattle was studied for 13 genetic-biochemical systems in relation to the differentiation of animals by sex, age color, birth weight and the weight increase during the first 6 months of life. The greatest value of genetic distance was revealed between animal groups, distinguished by the weight increase. The locus of purine nucleoside phosphorylase greatly contribute to this genetic differentiation.
针对乌克兰肉牛13个遗传生化系统的品种内基因型异质性进行了研究，研究内容涉及按性别、年龄、毛色、出生体重以及出生后前6个月的体重增加情况对动物进行区分。在按体重增加情况区分的动物组之间，发现了最大的遗传距离值。嘌呤核苷磷酸化酶基因座对这种遗传分化有很大贡献。
