为了确定两种日本青鳉（Oryzias latipes和Oryzias sakaizumii）在其自然环境中的杂交的实际状态，我们使用10个位点的核DNA标记分析了来自日本Yura河流域中游的8个野生种群的215个个体。尽管这两个物种之间存在较大的遗传差异，但它们之间的生殖隔离无法得到证实。本文还讨论了这两个种在尤拉河流域的现代分布格局及其杂交带的形成。
To determine the actual state of hybridization between two Japanese medaka species (Oryzias latipes and Oryzias sakaizumii) in their natural environment, we used nuclear DNA markers at 10 loci to analyze 215 individuals from eight wild populations in the middle reaches of the Yura River basin in Japan, where the two species are sympatric. Despite large genetic differentiation between the two species, reproductive isolation between them could not be confirmed. We also discussed the formation of the current distribution patterns of the two species and their hybridization zone in the Yura River basin.
