| Abstract: | Microsatellites are composed of tandemly repeated,simple DNA sequence motifs of 1-6 nucleotides in length.The mierosatellite 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,polytocous traits and birth weight was summarized in the review. |
