Abstract
Genetic structure and variation of seven natural Drosophila populations was analyzed at nine enzyme loci. The populations examined exhibited low levels of genetic polymorphism and heterozygosity (Hobs = 0.096). Interpopulation variation accounted for only 1.3% (Fst = Gst = 0.013), and the populations examined were shown to be genetically similar, as Dn did not exceed 0.001.
摘要
在九个酶位点上分析了七个果蝇自然种群的遗传结构和变异。所检测的种群表现出低水平的遗传多态性和杂合性（观测杂合度Hobs = 0.096）。种群间变异仅占1.3%（固定指数Fst = 基因分化系数Gst = 0.013），并且所检测的种群在遗传上相似，因为遗传距离Dn不超过0.001。
