With the rapid development of molecular biology and genetics, genome research has been from the level of patterns to the molecular level. Genetic polymorphism of the DNA molecular level has the increasing attention. Here, the discovery, classification and characteristics of the DNA polymorphism,as well as testing methods are analyzed systematically. And there is a brief summary of the DNA polymorphism in medicine, forensic science, and anthropology applications. DNA genome is the basis of biological diversity; with more in-depth study of DNA polymorphism, it will better serve the biomedical research and awareness.
