【摘要】 遗传多样性水平是一项很重要的数据。目前，从分子水平量化遗传多样性的方法以等位酶分析、ＲＦＬＰ分析和ＲＡＰＤ分析为代表。遗传变异在基因组中并非随机分布，所以取样方式对分析结果的影响不容忽视。本文叙述了遗传变异的产生和分布，并以此为基础比较了上述３种分析方法的理论与实践。更多还原

【Abstract】 Restriction fragments length polymorphism analysis (RFLP),and random amplified polymorphic DNA (RAPD),and allozyme analysis are three representatives of the various techniques used in the estimation of genetic diversity at molecular level.Genetic variation is not randomly distributed through the genome.Thus,the pattern of sampling will affect the result of analysis to some degree.RAPDs,as a genetic marker utilized by the population biologists,has its advantages.更多还原
