Abstract:
Two chromosome markers of Mus hortulanus are described: a dotted Y chromosome exceeding half of the length of autosome 19, and the 'domesticus' type of C-banding in the X chromosome. In Mus musculus from distant regions of the USSR (more than 200 specimens of various subspecies), the Y chromosome is equal to autosome 19, and the X chromosome is of the 'molossinus' type. Specific biochemical characteristics of house mice of the USSR are shown.
