Genetic polymorphism of sheep hemoglobin

Creator:: Templeton, Joe Wayne, 1941-
Abstract:: Five breeds of sheep (Columbia, Targhee, Rambouillet, Lincoln, and Suffolk) were found to possess two hemoglobin types (Hb. A and Hb. B) when their hemoglobins were examined by disc gel electrophoresis. The hemoglobin alleles proved to be co-dominant. Three of the breeds (Columbia, Targhee, and Rambouillet) were maintained at altitudes...

Effectiveness of index and elite selection methods

Creator:: Douglass, Larry W.
Abstract:: Mice were used to compare the index and elite selection methods for simultaneous selection of four traits. Selection was for litter size, birth weight, weaning weight and post-weaning gain. Progress was evaluated by examining total phenotypic merit. The standard deviations from the cycle mean for the four traits were summed...

Response of scorbutic guinea pigs to ascorbic acid and adrenocorticotropic hormone (ACTH)

Creator:: Riker, Joseph Thaddeus III
Abstract:: Thirty-six female guinea pigs were placed on a scorbutogenic diet for 14 days and then divided into groups of four. Three groups received adrenocorticotropic hormone (ACTH) with each group given 10, 20, or 40 units. Three groups each received 50 mg of ascorbic acid and three groups received 50 mg...

Influence of chelating agents on cytological exchanges and genetic recombination in Zea mays L.

Creator:: Jones, Donald Dean
Abstract:: The present investigation with the chromosomes of Zea mays was conducted to determine: (1) the effects of chelating agents on the process of cytological exchange, and (2) the effects of chelating agents on genetic recombination. To ascertain the influence of chelating agents on cytological exchange, four known heterozygolis paracentric inversion...

Actual and predicted response to selection on maternally influenced traits in the mouse

Creator:: Lind, Ronald Egnard
Abstract:: An experiment was conducted to determine if selection from standardized litters would be effective in separating lines of mice selected for increased and decreased litter weight at 14 days of age, and if response to selection on this maternally influenced trait could be accurately predicted. Data were collected on litter...

Selection applied, response of traits and combining abilities of inbred lines of beef cattle

Creator:: Hoornbeek, Frank K. (Frank Kent), 1928-
Abstract:: The investigations reported are based on two studies; the first is concerned with the selection practiced for performance in one inbred Angus and three inbred Hereford lines of cattle, the realized responses, levels of inbreeding and associated performance, and heritabilities of the performance traits. Selection differentials for all performance traits...
