It is argued that behavior genetics should be part of social policy deliberations because behavior genetics studies can reveal which traits are more influenced by shared environments and thus are most malleable through environmental change. This is of particular interest in the case of IQ. (SLD)

Agricultural communications students (n=330) from 11 universities were most aware of biotechnology effects on food, less aware of effects on health and the environment. They were somewhat accepting of genetic modifications for plants, not humans. Sources of biotechnology knowledge were science classes, labs, and university professors' beliefs.…

Presents modeling ideas for teaching about DNA using a climbing rope, rope ladder, paper, and CD cases. (YDS)

Describes a research program that provides insight into the nature of phylogenetic problems and problem-solving methods and how these might be applied to teaching evolution. Contains a new description of the nature of phylogenetic problems and factors contributing to their difficulty. (AIM)

Presents a lab that investigates the evolution of genetic resistance, the importance of genetic variability in the process of adaptation, and the ecological and economic consequences of pesticide use. Allows students to investigate the relationship between population size, genetic variability, and adaptability. Appendices contain the genetic card…

Interprets Edward Spranger's "Forms of Life" against the background of the findings of modern biology. Shows how far Spranger's diagnosis of different human types, which are not affected by external influences on characteristics, conform with research hypotheses of modern biological sciences. (CAJ)

This article examines the clinical aspects of etiology-related behaviors in young children with genetic mental retardation syndromes. Discussion of the concept of behavioral phenotype leads to consideration of how interventionists can best provide more focused and more effective interventions for children with different genetic disorders and…

Argues that a thorough understanding of factors that influence aggression in children cannot be achieved without including behavior genetic studies that allow examination of the effects of shared versus non-shared environment, as well as genes, on aggressive behaviors. Details the growing body of evidence on the genetic effects on aggression.…

Presents a 30-word wordsearch puzzle on nucleotide sequences used in proteins in terrestrial organisms. (YDS)

Claims little factual evidence exists for proposition that child rearing styles and family environments are formative of personality traits. Contends nonintellectual traits seem to be determined instead by genetic influences and relatively specific environmental influences, most of which are particularly tied to the family or parental treatments.…

Presents insights into the endosymbiotic theory based on a re-examination of evidence from investigations into the archaebacteria and other strange organisms inhabiting the hindguts of wood-eating insects. Examines the mechanism of evolutionary change and the speed with which it occurs. (RT)

Described is a simple technique for isolating DNA from halophilic bacteria. Materials, procedure, and additional experiments are outlined. It is stated that the DNA obtained will be somewhat contaminated with cellular proteins and RNA. Offers a procedure for greater purification. (RT)

Described is an activity in which students are able to determine that DNA can be transferred between bacteria and should be able to predict the type of DNA transferred. Methods, materials, and results are discussed. (CW)

Contends that the natural science curriculum does not prepare biology students for understanding the process of evolution. Proposes improved teaching approaches related to geological time, the natural transition of earth environments, the variability and alteration of genetic makeup, and the biological potential of species as being necessary for…

Research for biological-genetic markers of alcoholism is discussed in context of a multifactorial, heterogeneous, developmental model. Suggested that strategies used in linkage and association studies will require modification. Also suggested several extant associations of genetic markers represent true secondary interactive phenomena that alter…
