Interactions between genetic and environmental factors determine direction of population lateralization
نویسنده
چکیده
Direction of the embyro's head rotation is determined by asymmetrical expression of several genes (such as shh, nodal, lefty, and fgf8) in hensen's node. this genetically determined head-turning bias provides a base for light-aligned population lateralization in chicks, in which the direction of the lateralization is determined by genetic factors and the degree of the lateralization is determined by environmental factors.

The increasing susceptibility of broiler chickens to ascites syndrome has coincided with a continuing genetic and nutritional improvement in their feed efficiency and growth rate. Ascites is multifactorial and interactions between environmental and endogenous factors play a particularly important role. The selection of fast growing broilers for high feed efficiency, which is characterized by hy...

In this study, feature selection approach of logic regression was used to ide...
متن کاملP30: Are There Anxious Genes?
Anxiety comprises many clinical descriptions and phenotypes. A genetic predisposition to anxiety is undoubted; however, the nature and extent of that contribution is still unclear. Extensive genetic studies of the serotonin (5-hydroxytryptamine, 5-HT) transporter (5-HTT) gene have revealed how variation in gene expression can be correlated with anxiety phenotypes. Complete genome-wide linkage s...
متن کاملAge-Related Differences and Heritability of the Perisylvian Language Networks.
UNLABELLED Acquisition of language skills depends on the progressive maturation of specialized brain networks that are usually lateralized in adult population. However, how genetic and environmental factors relate to the age-related differences in lateralization of these language pathways is still not known. We recruited 101 healthy right-handed subjects aged 9-40 years to investigate age-relat...
