Inheritance of Patterns of Oxygen Consumption in Mice

Abstract

Oxygen consrnnptions were measured for males from three random-breeding mouse stocks, R70, Wild, and TNa, and for Fl and F2 offspring of R70xWild crosses and of R 70 X TN a crosses. In each group consumptions were measured on two occasions, once when the animals were adjusted to their rearing temperature (21°C) and once after they had been acclimatized to 33°C for 2 weeks. On both occasions consumptions were measured at air temperatures of 26, 28, 30, 32, and 34°C.
