Second chromosomes of D. melanogaster were isolated from a single natural population, and 40 were analyzed by gel-sieving electrophoresis for the presence of polymorphic loci on chromosome 2 that act to modify xanthine dehydrogenase and/or aldehyde oxidase, whose structural genes map to chromosome 3. Clear evidence of polymorphism for one or more xanthine dehydrogenase modifier loci was obtained.
黑腹果蝇的第二染色体是从一个单一自然种群中分离出来的,对其中40条染色体进行了凝胶筛分电泳分析,以检测2号染色体上是否存在可修饰黄嘌呤脱氢酶和/或醛氧化酶的多态位点,其结构基因定位于3号染色体上。获得了一个或多个黄嘌呤脱氢酶修饰位点存在多态性的明确证据。
