Musical aptitude is commonly measured using tasks that involve discrimination of different types of musical auditory stimuli. Performance on such different discrimination tasks correlates positively with each other and with intelligence. However, no study to date has explored these associations using a genetically informative sample to estimate underlying genetic and environmental influences. I...

Face processing and facial emotion recognition were investigated in five post-encephalitic people of average or above-average intelligence. Four of these people (JC, YW, RB and SE) had extensive damage in the region of the amygdala. A fifth post-encephalitic person with predominantly hippocampal damage and relative sparing of the amygdala (RS) participated, allowing us to contrast the effects o...

Breeding objectives were developed for Targhee sheep under rangeland production conditions. Traits considered were those for which EPD were available from the US National Sheep Improvement Program and included direct and maternal effects on 120-d weaning weight (WW and MM, respectively); yearling weight (YW); yearling fleece weight, fiber diameter, and staple length; and percent lamb crop (PLC)...

Records for the French national Large White sire line were collected between 1999 and 2008 for 65,082 pigs on farm and for 2,429 carcases of siblings measured in three test stations. Ultrasonic measures of backfat and muscle depth were recorded in vivo on farm. In addition, fat and muscle depth as well as length were recorded on carcases of littermates. Weights of primal cuts included back leg,...

OBJECTIVE-To estimate heritabilities and genetic correlations among 4 traits of hip joints (distraction index [DI], dorsolateral subluxation [DLS] score, Norberg angle [NA], and extended-hip joint radiograph [EHR] score) and to derive the breeding values for these traits in dogs. ANIMALS-2,716 dogs of 17 breeds (1,551 dogs in which at least 1 hip joint trait was measured). PROCEDURES-The NA was...

An important step in plant breeding programs is identification of parents that are geneticallydistant from each other, to find crossing combinations with better prospects of hybrid vigor. Thepotential of identifying genetically distant parents depends on genetic diversity of population. 58 linesof rice from diverse origins have been employed to study genetic variation in order to identify themo...

The feasibility of diagnostic reasoning in a Bayesian belief network, based on a genetic algorithm is demonstrated. The reasoning process described here is an example of approximate reasoning. Since exact abduction in a network modelling the "classical diagnostic problem" is NP-hard, inexact or approximate reasoning attracts much attention. The results of the present study indicate that in a gi...

The introduction of closely related species genomic fragments is an effective way to enrich genetic diversity and creates new germplasms in crops. Here, we studied the genetic diversity of an introgression line (IL) population composed of 106 ILs derived from an interspecific tetra cross between O. glaberrima and O. sativa (RAM3/Jin23B//Jin23B///YuetaiB). The proportion of O. glaberrima genome ...

The social behavior of animals, which is partially controlled by genetics, is one of the factors involved in their adaptation to large breeding groups. To understand better the relationships between different social behaviors, fear behaviors and production traits, we analyzed the phenotypic and genetic correlations of these traits in Japanese quail by a second generation crossing of two lines d...
