Nucleotide sequences of eight linked genes on mouse chromosome 8 were determined using wild mouse specimens representing the three major subspecies groups of M. m. domesticus (DOM), M. m. castaneus (CAS), and M. m. musculus (MUS) mice from Eurasia [13, 25] (a). Median joining networks of the Fanca and Dbndd1 genes are shown as representative examples of low and highly divergent states, respectively, of the subspecies group (MUS) (b). A neighbor-net network with concatenated sequences (n = 196) exhibits clusters of the three major subspecies groups and a variety of recombinant haplotypes [13] (c). The two putative phylogroups of MUS are designated MUS-I and MUS-II [25]. A schematic view of the geographic subdivisions of the Mus musculus musculus house mouse subspecies groups (MUS) (d). The subdivision of the house mouse into the tentatively designated phylogroups musculus and wagneri has been inferred from morphological, ecological, cytogenetic, electrophoretic, and molecular studies (e.g. [25, 2831]). Three possible source areas of the human-associated prehistoric dispersals of MUS are marked with star symbols: 1) Transcaucasia, 2) Turkmenistan/Kazakhstan, and 3) the Taklamakan Desert (see text)
