微卫星序列是以1～6个短核苷酸为基本重复单位的重复序列，呈共显性、重复性好、多态性丰富和操作简单，在基因定位与QTL分析、亲权分析、分子标记辅助选择等方面应用广泛。本文综述了与肉牛部分经济性状（生长发育性状、胴体性状、肉质性状、多胎性状和出生重）相关的微卫星标记研究进展。

Microsatellites are composed of tandemly repeated, simple DNA sequence motifs of 1- 6 nucleotides in length. The microsatellite analysis was extensively used in gene mapping, QTL analysis, parentage determination, marker--assistant selection and so on due to the characteristics of codomiant, good repeatability, high polymorphism, and simple manipulation. The research progress of microsatellite markers related with several economic traits of beef cattle including growth and development trait, carcass trait, meat quality trait, poly...
