Abstract
Restriction fragment length polymorphism (RFLP) analysis has been used to evaluate mitochondrial DNA (mtDNA) variation in 12 sibling species forming the Drosophila virilis species group. The variation thresholds corresponding to the interspecific and interstrain levels have been determined. The results indicate that interspecific hybridization has significantly contributed to the evolutionary history of the virilis species group.
摘要
限制性片段长度多态性（RFLP）分析已被用于评估构成果蝇种组的12个姊妹种中线粒体DNA（mtDNA）的变异。已经确定了对应于种间和菌株间水平的变异阈值。结果表明，种间杂交对果蝇种组的进化历史有显著贡献。
