Abstract

The association between mtDNA haplotypes and chromosomal arrangements in a natural population of Drosophila subobscura from Calvia (Balearic Islands, Spain) was studied in order to search for linkage disequilibria, in an attempt to explain the populational dynamics of the mtDNA haplotypes of this species in nature. The presence of Wolbachia was not detected. Two main haplotypes (I and II) were found, as well as a series of less common ones. The Tajima D-test seemed to indicate some kind of seasonal population bottleneck. An analysis of linkage disequilibrium and factorial analysis of correspondences detected an association between haplotype I and the J(ST) inversion and haplotype II and the J(1) inversion.

摘要

为了寻找连锁不平衡，以解释该物种线粒体DNA单倍型在自然环境中的群体动态，我们研究了来自西班牙巴利阿里群岛卡尔维亚的一个自然果蝇群体中线粒体DNA单倍型与染色体排列之间的关联。未检测到沃尔巴克氏体的存在。发现了两种主要的单倍型（I和II）以及一系列不太常见的单倍型。 Tajima D检验似乎表明存在某种季节性种群瓶颈。连锁不平衡分析和对应分析检测到单倍型I与J(ST)倒位以及单倍型II与J(1)倒位之间存在关联。
