Abstract:

SNP (single nucleotide polymorphism) marker, as a molecular marker of the third generation, plays an important role in molecular genetics, pharmacogenetics, forensic medicine, diagnosis and treatment of diseases recently. In this paper, the definition and characteristics of SNP molecular marker were both introduced. And the application profiles of Bin map, high throughput SNP-chip classification and population evolution research on the basis of SNP molecular marker was presented respectively. Finally, the problems of SNP molecular marker at the present stage were proposed, and the prospects of SNP molecular marker was predicted as well.
