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...

Estimation of general and specific combining abilities from a diallel cross of three inbred lines of Suffolk sheep

Creator:

Schilling, Prentiss E. (Prentiss Edwin), 1941-

Abstract:

The investigations were based on a complete diallel cross among three inbred lines of Suffolk sheep. Line of sire effects were assumed to be an estimate of general combining ability effects while sire x dam interaction was assumed to be an estimate of specific combining ability. The line of dam...

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...
