【摘要】 单核甘酸多态性（ SNPs）是继 RFLP和微卫星多态性标记之后的新一代遗传标记系统，具有密度高、遗传稳定、分析易自动化等特点。 SNPs可通过电泳、 PCR、酶切及测序等方法检测，已广泛应用于基因作图、疾病相关性分析、群体遗传学及药物研究等领域。更多还原

【Abstract】 Single nucleotide polymorphisms (SNPs) is a new genetic marker system following RFLP and microsatellite polymorphism. It has been shown to have the characteristics of high－ density, inheritance stability and facilitation in analysis automation. SNPs can be detected by electrophoresis, endonuclease－ cleavage, PCR and sequencing, and can be used extensively in gene mapping, disease－ correlativity analysis, population genetics and drug research.
