The ASAP1 gene is located in a QTL region for meat production traits and to access the role of the ASAP1 gene, the association between a SNP in this gene and production traits in beef cattle was studied. For this, about 270 steers of reference families of Nelore breed were used. The investigation of marker effects on the traits was performed using a mixed model under the restricted maximum likelihood method. Novel association of a SNP in the ASAP1 gene and shear force measured at 24 h post mortem (P≤0.0083) was described in this population of Nelore cattle. This polymorphism accounted for 1.13% of the total additive variance and 17.51% of total phenotypic variance of the trait, suggesting that this marker could be used in marker assisted selection.
ASAP1 基因位于一个与肉质生产性状相关的 QTL 区域。为了研究 ASAP1 基因的作用，研究了该基因中的 SNP 与肉牛生产性状之间的关联。为此，使用了大约 270 头参考家庭的内罗尔牛。使用混合模型在约束极大似然法下对标记对性状的效应进行了调查。在这个内罗尔牛群体中，描述了 ASAP1 基因中的 SNP 与死后 24 小时测量的剪切力之间的新关联（P≤0.0083）。该多态性占性状总加性方差的 1.13%和总表型方差的 17.51%，表明该标记可用于标记辅助选择。
