Effects of radiation on selection progress in mice

Creator:: Womack, James Ernest
Abstract:: The effects of x-irradiation on quantitative genetic traits was investigated by comparing the response of irradiated mice to selection for litter size and 28-day weight with the response to selection for the same two traits in non-irradiated lines. Irradiated lines were maintained at three levels of x-irradiation, 25 r, 50...

Genetic polymorphism of sheep hemoglobin

Creator:: Templeton, Joe Wayne, 1941-
Abstract:: Five breeds of sheep (Columbia, Targhee, Rambouillet, Lincoln, and Suffolk) were found to possess two hemoglobin types (Hb. A and Hb. B) when their hemoglobins were examined by disc gel electrophoresis. The hemoglobin alleles proved to be co-dominant. Three of the breeds (Columbia, Targhee, and Rambouillet) were maintained at altitudes...
