Restriction analysis shows that wild Scandinavian mice belonging to the species Mus musculus contain the mitochondrial DNA of a neighboring species, M. domesticus. This demonstration results from comparisons of Scandinavian mice with authentic M. domesticus and M. musculus from other parts of Europe. Electrophoretic and immunological analysis of eight diagnostic proteins confirms that mice from north of the hybrid zone in Denmark are M. musculus in regard to their nuclear genes. In contrast, the mice tested from this region and a nearby part of Sweden have exclusively M. domesticus types of mitochondrial DNA. Phylogenetic analysis of the restriction maps suggests that the mitochondrial DNAs found in Scandinavian M. musculus could stem from a single M. domesticus female.
限制性分析表明,属于小家鼠物种的野生斯堪的纳维亚小鼠含有邻近物种家鼠的线粒体DNA。这一发现源于对斯堪的纳维亚小鼠与来自欧洲其他地区的正宗家鼠和小家鼠进行的比较。对八种诊断蛋白的电泳和免疫分析证实,丹麦杂交区以北的小鼠在核基因方面属于小家鼠。相比之下,从该地区和瑞典附近地区测试的小鼠仅具有家鼠类型的线粒体DNA。对限制性图谱的系统发育分析表明,在斯堪的纳维亚小家鼠中发现的线粒体DNA可能源自一只家鼠雌性个体。
