Three groups of ewe lambs born in May (experiment 1; n=211) or April (experiment 2; n=174) were used to evaluate the effects of selection line and induction of estrus on pregnancy rate. Experiment 1 was a single factor experiment with induction of estrus as the main effect. In early December, May-born Targhee (n=82) and Rambouillet x Targhee (n=129) ewes were randomly assigned within body weigh...
Genetic regulation of acute tolerance to ethanol may be associated with ethanol consumption and other ethanol-related behaviors in rodents. We have used lines of mice, selectively bred for high and low acute functional tolerance (HAFT and LAFT, respectively) to ethanol-induced loss of balance to test this hypothesis. Replicate HAFT and LAFT lines differ in AFT to ethanol-induced loss of balance...
Female mice from independently bred lines previously selected over 50 generations for increased voluntary wheel-running behavior (S1, S2) resist high energy (HE) diet-induced obesity (DIO) at adulthood, even without actual access to running wheels, as opposed to randomly bred controls (CON). We investigated whether adult S mice without wheels remain DIO-resistant when exposed - via the mother -...
It is estimated that more than 95% of organic agriculture based on crop cultivars were bred for the conventional high-input sector. Most selections made through breeding programs and lack important traits required under low-input conditions. Hybrids are most common type used in tomato because heterosis. In tomato, continuous selfing enabled homozygosity to exploit favorable additive genes, resu...
Little is known about how genetic variation affects the capacity for exercise to change body composition. We examined the extent to which voluntary exercise alters body composition in several lines of selectively bred mice compared to controls. Lines studied included high runner (HR) (selected for high wheel running), M16 (selected for rapid weight gain), Institute of Cancer Research (ICR) (ran...
A 3D-variational data assimilation scheme for a quasi-geostrophic channel model (Morss, 1998) is used to study the structure of the background error and its relationship to the corresponding bred vectors. The “true” evolution of the model atmosphere is defined by an integration of the model and “rawinsonde observations” are simulated by randomly perturbing the true state at fixed locations. Cas...
UNLABELLED Aims/Introduction: The development of type 2 diabetes is primarily due to lifestyle and environmental factors, as well as genetics, as shown by familial clustering. To establish mouse lines for evaluating heritable factors determining susceptibility to diet-induced diabetes, we performed selective breeding for differences in high fat diet (HFD)-induced glucose intolerance.
