SummaryMice are the most widely used experimental mammals, and many inbred strains are available. However, except for the relatively recent strains derived from known wild populations, the relationships between wild and laboratory mice are not well understood. Based on the Y-chromosomal restriction fragmentlength polymorphism, seventeen inbred strains were classified into two groups: strains with the Mus musculus musculus type Y chromosome and those with the M. m. domesticus type Y chromosome. We extended the survey to an additional twenty-two inbred strains. The M. m. musculus type Y chromosome was found in AEJ/GnLe, AAU/SsJ, BDP/J, BXSB/MpJ, DA/HuSn, HTG/GoSfSn, I/LnJ, LP/J, NZW/LacJ, RIIIS/J, SB/Le, SEA/GnJ, SF/CamEi, SK/CamEi, SM/J, WB/ReJ, WC/ReJ and YBR/Ei, while the M. m. domesticus type Y chromosome was present in BUB/BnJ, MA/MyJ, PL/J and ST/bJ.

Adult animals have been used for most of the previous mammalian temperature selection studies, and relatively few systematic observations have been made with young animals. In this investigation, laboratory mice (Mus musculus), ranging in age from 1 to 84 days, were studied in a horizontal temperature gradient established along a 5-ft copper bar. Despite poorly developed locomotion and cold immobilization, it was shown that the temperature selection response is present at birth. The initially high level of selection appeared to be maintained for about 2 weeks, after which it began to decrease, rapidly at first, and then more slowly until the adult level was reached.
