Abstract
The phenotype traits of livestock are determined by the genetic variation with environmental variation of individual animals. In the past, the classification of breed was depending on morphological characteristics to identify breed. However, in recent years, various genetic markers can be analyzed to identify different breeds and individual animals. These molecular genetic markers can be used to assess the genetic diversity as well as tracking the species origin and identification. Recently, a genome sequencing technology can be rapidly and accurately confirmed the various type of genetic markers in the entire genome area. Of these, developed SNP markers and the rapidly evolving SNP array technology are increasingly replacing genetic diversity analysis using microsatellite markers. Therefore, this review discussed the basic information for developing various molecular genetic markers and their use in genetic diversity studies of livestock animals.
