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...

Creator:: Wong, Patrick Tin-Choi, 1942-
Abstract:: The effect of X-irradiation on DNA synthesis in larval salivary glands of Drosophila hydei was studied using the technique of liquid scintillation spectrometry and autoradiography. DNA synthesis in salivary glands of synchronized larvae was measured at successive stages of third instar development by in vitro uptake of ³H-thymidine for a...

Creator:: North, Warren Arthur
Abstract:: There were two studies involved in the thesis research. In the first study, variation in the amount of adenohypophysis gonadotropins among 22 individual beef bulls were investigated. These bulls represented four inbred lines, and six linecrosses. The bulls were raised in the Oregon State University purebred herd. The bulls were...
