Western european house mouse
Mus musculus domesticus, the Western European house mouse, is a subspecies of the house mouse (Mus musculus ). Some laboratory mouse strains, such as C57BL/6, are domesticated from M. m. domesticus.
In Europe, M. m. domesticus lives in Western and Northern Europe, while another subspecies, the Eastern European house mouse (M. m. musculus ) lives in Eastern and Southern Europe. The area from Scandinavia to the Black Sea is a secondary hybrid zone for M. m. domesticus and M. m. musculus. Habitats of M. m. domesticus also exist in the Middle East, Southern Asia, North Africa, North America, and some areas of Latin America and Oceania.
