进行了实验室笼子实验，以研究白纹伊蚊在两种条件下（双向相容交配和单向不相容交配）下两种线粒体 DNA (mtDNA) 单倍型频率随时间的变化。对于上述两种条件中的每一种，在三个重复笼中监测 10 代的频率。在具有双向相容品系的笼子中，单倍型频率的变化是无方向性的，并且两种单倍型的频率都没有增加。对每一代中两种单倍型相对比例的统计分析表明，仅在随机遗传漂变的假设下就可以预期观察到的波动的幅度。在单向不亲和交配的笼子中，与另一品系的雄性交配后产下不能存活卵的雌性的线粒体DNA在F1代中显着减少，并在F2代中被完全取代。
A laboratory cage experiment was undertaken to study changes over time in the frequencies of two mitochondrial DNA (mtDNA) haplotypes in the mosquito, Aedes albopictus, under two conditions: bidirectionally compatible matings and unidirectionally incompatible matings. Frequencies were monitored for 10 generations in three replicate cages for each of the two conditions above. In cages with bidirectionally compatible strains, changes in haplotype frequencies were nondirectional and neither haplotype increased in frequency. Statistical analysis of relative proportions of the two haplotypes in each generation indicated that the magnitude of the observed fluctuations could be expected under an assumption of random genetic drift alone. In cages with unidirectionally incompatible matings, mtDNA of females that lay inviable eggs upon mating with males of another strain, decreased significantly in the F1 generation and was completely replaced in the F2 generation.
