Abstract
Genetic variability of D. sechellia is investigated at both mitochondrial and nuclear levels. The results reveal the existence of a single main type of mtDNA with very few variants and a very low enzyme polymorphism. This situation is consistent with the small population size of this specialized species.
摘要
对塞舌尔果蝇的遗传变异性进行了线粒体和核水平的研究。结果显示存在单一主要类型的线粒体DNA，变异极少，酶多态性也很低。这种情况与这种特殊物种的小种群规模相一致。
