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...

Estimates of combining abilities, heterotic effects and phenotypic correlations among in-bred lines of beef cattle and their line-crosses

Creator:: Humes, Paul Edwin
Abstract:: The investigations were based on a complete diallel cross among three inbred lines of Hereford cattle. Records of Angus calves born during the same period were used to obtain more accurate estimates of environmental effects and to determine breed differences among the various traits included in the study. Estimates of...

Genetic parameters of the house fly (Musca domestica Linn.)

Creator:: Konanta, Sugsanguan
Abstract:: Eight strains of housefly, Musca domestica Linn., from two laboratories were intercrossed to form a stock population. Virgin males and females from the stock were collected, and nine sets, each consisting of twelve males mated to five females, were successively done. Pupae weight, adult weight, emergence time and egg production...

Morphology of epididymal spermatozoa from inbred and linecross bulls

Creator:: Turner, H. A.
Abstract:: Data were presented on epididymal spermatozoa from 29 inbred and linecross bulls raised at Oregon State University in connection with the Western Regional Beef Cattle Breeding Project, W-1. The inbred bulls came from four inbred lines. Three of these inbred lines were Herfords and the other line was Angus. The...

Genetic and physiological factors associated with gonadotropic and thyrotropic hormone content of sheep pituitaries

Creator:: Plotka, Edward Dennis
Abstract:: Data were taken from 47 animals consisting of five breeds: Border Cheviot, Columbia, Dorset Horn, Suffolk, and Willamette. Both sexes were represented in each breed, although in unequal numbers. The pituitaries were assayed for gonadotropic and thyrotropic hormone content by injecting a suspension of the macerated gland in saline into...
