This study aims to find the association between gene polymorphism and growth traits at different ages, such as birth, 3rd-month, 6th-month and 12th-month ages in Anatolian black cattle. PCR-RFLP method was used to detect the polymorphism for gene in at G61595A locus. Allele and genotype frequencies were A: 0.34, G: 0.66 and AA: 0.17, AG: 0.34 and GG: 0.49. The chi-square test showed an agreement to Hardy-Weinberg equilibrium ( > .01). GLM and RRM models were used to estimate the association between gene polymorphism and growth traits. The results of the statistical analysis indicated an association between gene polymorphism and growth traits at different stage ages in Anatolian black cattle. Therefore, the G61595A mutation of gene can be used as a genetic marker for the selection of growth and development traits in the cattle breeding programs.
本研究旨在探讨安纳托利亚黑牛生长性状在不同年龄（如出生、3 月龄、6 月龄和 12 月龄）之间与基因多态性的关联。采用 PCR-RFLP 方法检测 G61595A 位点基因的多态性。等位基因和基因型频率分别为 A：0.34、G：0.66 和 AA：0.17、AG：0.34 和 GG：0.49。卡方检验显示 Hardy-Weinberg 平衡（ > .01）。GLM 和 RRM 模型用于估计基因多态性与生长性状之间的关联。统计分析结果表明，基因多态性与安纳托利亚黑牛不同阶段年龄的生长性状之间存在关联。因此，基因的 G61595A 突变可以作为牛育种计划中生长和发育性状选择的遗传标记。
