Statistical data from breeding experiments suggested that a
reciprocal chromosomal translocation had spontaneously occurred in
a line of S. C. White Leghorn fowl. Approximately 50% of the
embryos from matings between suspected translocation heterozygotes
and normal birds died early during incubation. In an effort
to obtain cytological proof of this...

Several experiments were conducted with birds differing in body weight, conformation and sternal measurements to obtain information on whether it would be possible during short term selection to influence the shape of the sternum and, if so, what influence this would have on the amount and distribution of the breast...
A number of studies with ¹⁴C-labeled 2-chloro-2', 6'-diethyl-
N-(methoxymethyl) acetanilide
(alachlor) were conducted to obtain
information about the mechanisms
of uptake of this herbicide.
In other studies, technical
alachlor as well as the emulsifiable
concentrate formulation of the
chemical were used to investigate the
effect of several factors on the...

Chromosomal rearrangements may complicate construction of Arabidopsis with multiple TDNA-insertion mutations. Here, crossing two lines homozygous for insertions in AtREV3 and AtPOLH (chromosomes I and V, respectively) and selfing F1 plants yielded non-Mendelian F2 genotype distributions: frequencies of +/++/+ and 1/1 2/2 progeny were only 0.42 and 0.25%. However, the...
Sperm mobility denotes the net movement of a sperm population. Previous work implicated mitochondrial function as a basis underlying phenotypic variation in this quantitative trait. Our objective was to determine if mitochondrial function was indeed critical to expression of phenotype. Phenotype was assigned to roosters within a random bred population...
An attempt was made to create a hormonal environment of the
uterus comparable to that near the time of natural laying and to
eliminate the effect of a hard-shelled egg on fertilization. Hens without
hard-shelled eggs in their uteri were injected with the posterior
pituitary hormones, oxytocin and arginine vasopressin,...
