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...

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...
