Analyses of complete 1143-base pair sequence of the mitochondrial cytochrome b gene demonstrated a sister relationship between Japanese R. nigromaculata and Korean R. plancyichosenica, but not with Korean R. nigromaculata, while the allozyme data strongly supported the monophyly of the Korean and Japanese populations of R. nigromaculata. We surmise this discordance to be the result of the inheritance of introduced mtDNA and the dilution of introduced nuclear DNA in mixed lineages after past hybridization and genome introgression between the two species, although the direction of introgression is unknown.
对线粒体细胞色素b基因完整的1143个碱基对序列的分析表明,日本黑斑侧褶蛙与韩国普兰西侧褶蛙之间存在姐妹关系,但与韩国黑斑侧褶蛙不存在这种关系,而等位酶数据有力地支持了韩国和日本黑斑侧褶蛙种群的单系性。我们推测这种不一致是过去两个物种杂交和基因组渗入后,混合谱系中引入的线粒体DNA遗传以及引入的核DNA稀释的结果,尽管渗入的方向尚不清楚。
