Genetic variation at 43 loci has been studied in six different populations of Drosophila persimilis by electrophoresis of enzymes and proteins. In D. persimilis the mean proportion of polymorphic loci is 0.362, the mean proportion of heterozygous loci per individual is 0.100 and the average number of alleles per locus is 1.651. In all populations, the loci coding for the hydrolytic and other nonspecific enzymes are much more variable than the loci coding for the enzymes of the glycolytic pathway, Kreb's cycle, other specific enzymes and larval proteins. Most loci have similar allele frequency in all populations except the two loci, Amylase and Pt-12, which show a pattern of associations of different alleles with different third chromosome inversions.
通过电泳技术对 6 个不同种群的黑腹果蝇的 43 个基因座的遗传变异进行了研究。在黑腹果蝇中，多态性基因座的平均比例为 0.362，每个个体的杂合性基因座的平均比例为 0.100，每个基因座的等位基因平均数量为 1.651。在所有种群中，编码水解酶和其他非特异性酶的基因座比编码糖酵解途径、克雷布斯循环、其他特异性酶和幼虫蛋白的基因座的变异性大得多。除了 Amylase 和 Pt-12 这两个基因座之外，大多数基因座在所有种群中的等位基因频率都相似，这两个基因座的不同等位基因与不同的第三染色体倒位有关。
