Physiological and Morphological Characteristics of Mice Moved to 21°C after 10 Generations at 34°C

Abstract

The effects of maintaining mice for 10 generations at 34°C were measured by comparing the reproductive productivity, growth rate, oxygen consumption, hair growth, density of the subepidermal capillary net, and frequency of the pink-eye gene in mice selected for productivity at 34°C (R95), the same mice moved to 21°C (L95), controls at 21°C (R70), and offspring of crosses between R95 and R70 mice and an unrelated stock (Wild) kept at 21°C (W95 and W70)_
