"Advances in Genetics Research" presents original research results on the leading edge of genetics discovery. Each article has been carefully selected in an attempt to present substantial research results across a broad spectrum. In this continuing series compilation, the authors present and discuss varied topical data such as: genetic and biochemical markers of serotonergic and catecholaminergic systems in neuropsychiatric disorders; methodological aspects of gene flow estimation in natural populations; genetic structuring across the reef crest in the threatened blue coral heliopora; an overview of genetic factors and environmental triggers in the pathogenesis of Tourette's Syndrome; genetics and molecular biology of kainate receptors; and others.
