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...
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...
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...
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...
An experiment was conducted to examine the responses to
selection for high and low rate of gain in the mouse under a system
whereby inbreeding was maximized. Rate of gain was measured by an
index designed to include gains in both the pre- and postweaning
periods with the gains in...
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...
A total of 902 plasma samples from the Rambouillet, Targhee, Columbia, Lincoln, and Suffolk breeds of sheep were analyzed for transferrin type by disc electrophoresis. Six transferrin types, Tf[superscript A], Tf[superscript B], Tf[superscript C], Tf[superscript p], Tf[superscript E], and Tf[superscript P], were found in the Rambouillet, Targhee, and Columbia breeds...
