An analysis of the mode of gene action affecting pupa weight in Tribolium castaneum.
Triple-testcross experiments (Kearsey and Jinks 1968) were employed to investigate the mode of gene action affecting pupa weight in Tribolium castaneum. Their experimental design involves two inbred lines, the F1 progeny and a segregating population derived from the cross of the inbred lines. In the present experiments, four segregating populations were used. These populations included the F2 g...
متن کاملFood Consumption, Feed Efficiency, Metabolic Rate and Utilization of Glucose in Lines of TRIBOLIUM CASTANEUM Selected for 21-Day Pupa Weight.
Food consumption, feed efficiency, metabolic rate and glucose utilization were studied throughout development in one control (1C) and three selected lines (3, 9, 10) of Tribolium castaneum that had been subjected to long term selection for 21-day pupae weight. Growth rate, body composition, cellular growth and the activity of four dehydrogenase enzymes in the same lines have been reported (Medr...
متن کاملGrowth Rate, Body Composition, Cellular Growth and Enzyme Activities in Lines of TRIBOLIUM CASTANEUM Selected for 21-Day Pupa Weight.
Growth rate, body composition, cell number, cell size, and the activity of four dehydrogenase enzymes were studied from 10 to 25 days of age in one control (1C) and three lines (3, 9, 10) of Tribolium castaneum that had been subjected to long term selection for large 21-day pupae weight.-Selected lines were two- to three-fold larger in size than the control line throughout development. No major...
متن کاملRepair of x-irradiation damage in Tribolium castaneum strains selected for differences in development rates.
Lines previously selected for different speed of development were found to differ in their spontaneous and induced wing abnormalities after single exposure to X-ray (10 KR) in Tribolium castaneum at 33 degrees and 70% relative humidity. At the time of irradiation the mean developmental time (from egg to first day pupa) was 16.9, 18.8, 22.8 and 18.4 days for fast, intermediate, slow and unselect...
متن کاملAn Experimental Examination of Restricted Selection Index, Using TRIBOLIUM CASTANEUM. II. the Results of Long-Term One-Way Selection.
HE first seven generations of a selection experiment designed to allow exTperimental evaluation of a restricted selection index were reported by OKADA and HARDIN (1967). The index was computed to produce maximum response in 14-day larval weight of Tribolium castaneum while preventing a correlated increase in 30-day adult weight. Not only was the index effective for restricting the change of 30-...
