【Abstract】 The concept of genetic diversity and prinsiple and characteristic of random amplified polymorphic DNA (RAPD) analysis technique were introduced, and discussed with comments on its advantage and weakness and the scientific research, progress at home and abroad was summarized. RAPD analysis is an important method of studying the genetic diversity if organism, and has opened a broad prospects for the study of systematics and evolution with molecular data.更多还原
