Japanese house mice (Mus musculus molossinus) are thought to be a hybrid lineage derived from two prehistoric immigrants, the subspecies M. m. musculus of northern Eurasia and M. m. castaneus of South Asia. Mice of the western European subspecies M. m. domesticus have been detected in Japanese ports and airports only. We examined haplotype structuring of a 200 kb stretch on chromosome 8 for 59 mice from throughout Eurasia, determining short segments (approximately 370-600 bp) of eight nuclear genes (Fanca, Spire2, Tcf25, Mc1r, Tubb3, Def8, Afg3l1 and Dbndd1) which are intermittently arranged in this order. Where possible we identified the subspecies origin for individual gene alleles and then designated haplotypes for concatenated alleles. We recovered 11 haplotypes among 19 Japanese mice examined, identified either as 'intact' haplotypes derived from the subspecies musculus (57.9%), domesticus (7.9%), and castaneus (2.6%), or as 'recombinant' haplotypes (31.6%). We also detected recombinant haplotypes unique to Sakhalin. The complex nature of the recombinant haplotypes suggests ancient introduction of all three subspecies components into the peripheral part of Eurasia or complicated genomic admixture before the movement from source areas. 'Intact'domesticus and castaneus haplotypes in other Japanese wild mice imply ongoing stowaway introductions. The method has general utility for assessing the history of genetic admixture and for disclosing ongoing genetic contamination.

“…To further illustrate this point, mice with both DOM and CAS mtDNA haplotypes have been captured in Japanese international ports (Tsuda et al, 2007) and Nunome et al (2010a) provided robust evidence from their nuclear haplotype analysis of genetic introgression by DOM components of Japanese house mice. The extent to which genetic introgression may now be shaping the future evolution of the house mouse is an interesting topic-one that has bearing on other commensal mammals, including the black rat Rattus rattus which also displays comparable signals of former geographic sub-division and recent intermingling as a consequence of commensalism and human-assisted dispersal (Chinen et al, 2005;Aplin et al, 2011;Bastos et al, 2011;Lack et al, 2012).…”

We examined the sequence variation of mitochondrial DNA control region and cytochrome b gene of the house mouse (Mus musculus sensu lato) drawn from ca. 200 localities, with 286 new samples drawn primarily from previously unsampled portions of their Eurasian distribution and with the objective of further clarifying evolutionary episodes of this species before and after the onset of human-mediated long-distance dispersals. Phylogenetic analysis of the expanded data detected five equally distinct clades, with geographic ranges of northern Eurasia (musculus, MUS), India and Southeast Asia (castaneus, CAS), Nepal (unspecified, NEP), western Europe (domesticus, DOM) and Yemen (gentilulus). Our results confirm previous suggestions of Southwestern Asia as the likely place of origin of M. musculus and the region of Iran, Afghanistan, Pakistan, and northern India, specifically as the ancestral homeland of CAS. The divergence of the subspecies lineages and of internal sublineage differentiation within CAS were estimated to be 0.37-0.47 and 0.14-0.23 million years ago (mya), respectively, assuming a split of M. musculus and Mus spretus at 1.7 mya. Of the four CAS sublineages detected, only one extends to eastern parts of India, Southeast Asia, Indonesia, Philippines, South China, Northeast China, Primorye, Sakhalin and Japan, implying a dramatic range expansion of CAS out of its homeland during an evolutionary short time, perhaps associated with the spread of agricultural practices. Multiple and non-coincident eastward dispersal events of MUS sublineages to distant geographic areas, such as northern China, Russia and Korea, are inferred, with the possibility of several different routes.

Current phylogenetic analyses of relatively long sequences of mitochondrial DNA (4,225 bp) in the Japanese house mouse Mus musculus provided the first evidence that both southern Asian subspecies of Mus musculus castaneus (CAS) and northern Asian subspecies of M. m. musculus (MUS) arrived in Japan through rapid population expansion events, from Southern China ~4,000 years ago and the Korean Peninsula ~2,000 years ago, respectively. Nuclear DNA haplotype structure analyses targeted a chromosome region with two different tract sizes, 1 Mb and 5 Mb, consisting of nine and six tandemly arranged markers, respectively, yielding a possible average fragment length of 170 kb of CAS haplotypes in the MUS background genome in northern Japan, providing a rough estimate of its elapsed time of 815 generations under an assumption of continued backcrossing. Less frequent and shortened CAS-like haplotypes specific to Japan were detected, suggestive of ancient introduction prior to the appearance of the South Chinese CAS in Japan. Our analyses also showed sporadic appearance of long fragments (2-5 Mb) from the west European subspecies M. m. domesticus, indicating contemporary stowaway introduction. Overall, multiple overseas introductions, and the time-lagged inter-subspecies genetic admixture, likely resulted in the heterogeneous state of Japanese wild mice.
