Interactions Between Genetic And Environmental Factors Determine Direction Of Population Lateralization, Chao Deng
Faculty of Social Sciences - Papers (Archive)
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.
