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...

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...

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...

The relationship between x-ray induced teratogeny and chromosome aberrations in golden hamster embryos

Creator:: Jones, William Elvin
Abstract:: The relationship between x-ray induced chromosome aberrations and x-ray induced embryonic abnormalities was studied. Golden hamsters were irradiated during four stages of gestation: the blastocyst stage, 4.5 days post-copulation; the primitive streak stage, 6.5 days post-copulation; the organogenesis stage, 9.5 days post-copulation; and the period of fetal growth, 11.5 days...

A clinical and genetic study of tuberous sclerosis

Creator:: Edwards, Thomas Allen
Abstract:: Tuberous sclerosis is a serious heritable human disorder that involves many organ systems. It was first recognized as a disease entity over a century ago. Its mode of transmission in familial cases has been fairly well established to be that of a single gene locus autosomal dominant trait. However, the...

The comparison of two methods of evaluating inheritance of milk production of dairy sires

Creator:: Srinives, Supote
Abstract:: The production records used were all converted to a comparable based, 305 day lactation period, two times a day milking, and mature equivalent (305 days-2-x-ME) of 71 cows from four Holstein bulls and 59 cows from four Jersey bulls were used for the study. The Equal Parent Index, Regression Index...

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...
