Short Tandem Repeats (STR) in cattle genomics and breeding

Abstract

Molecular markers are essential tool for determining the specific genetic makeup of an individual and are valuable approach for genetic improvement of farm animals. In cattle breeding their application is useful for improvement of breeding programs for desired traits, better productivity and high quality products. These markers provide more accurate genetic information and better knowledge of the animal genetic resources. In this review we attempt to make a brief summary on the application of one of more advanced DNA-based molecular markers in cattle breeding, namely short tandem repeat (STR, microsatellites).
