With a spotlight upon current agricultural difficulties and environmental dilemmas, this paper considers both the extant and potential applications of genetic engineering with respect to crop production. The nonagricultural factors most likely to sway the impact of this emergent technology upon future crop production are illustrated. (JJK)

A research study of identical twins, by Thomas J. Bouchard Jr., discloses that genetics exert a stronger influence over personality than we thought. Parents and teachers are advised to be active and alert observers of children's interests and talents to provide appropriate tools and resources to develop these propensities. (MLF)

Two ethical concerns about the Human Genome Project, which aims to sequence all the DNA of a human cell, are discussed: (1) use of germ-line gene therapy to treat perceived hereditary defects or enhance supposed genetic attributes, and (2) personal privacy and potential discrimination arising from possession of individual genetic information. (MSE)

Results from a study of 82 males provide no statistical support and limited encouragement that genetic risk information may motivate persons to make positive changes in preventive health behaviors. Health risk assessments were used to identify subjects at risk for coronary heart disease or lung cancer because of genetic factors. (IAH)

Examines the "sib pair" method of linkage analysis designed to locate genes influencing dyslexia, which has several advantages over the "LOD" score method. Notes that the sib pair analysis was able to detect the same linkages as the LOD method, plus a possible third region. Confirms that the sib pair method is an effective means of screening. (RS)

Reports on the meiosis models utilized by five individuals at each of three levels of expertise in genetics as each reasoned about this process in an individual interview setting. Results revealed a set of biologically correct features common to all individuals' models as well as a variety of model flaws (i.e., meiosis misunderstandings) which are…

Provides examples of alternative assessment methods on the following topics: (1) microbiology assessment; (2) optics assessment; (3) genetics assessment; (4) electromagnetic assessment; and (5) student responses. (ZWH)

The frequency and clinical presentation of autism in 28 probands with tuberous sclerosis complex (TSC), an autosomal dominant disorder characterized by benign tissue growths and a high frequency of seizure disorders and mental retardation, was examined. Eight probands met criteria for autism. Implications for understanding the association of…

Whether genetic and environmental effects on academic achievement changed as a function of the quality of children's environment was studied with 1664 pairs of full siblings, 366 pairs of half siblings, and 752 pairs of cousins. Little evidence was found of genotype-environment interactions. (SLD)

Describes the "American Renaissance" Conference of 1998 at which 200 scholars from the extreme right gathered to discuss theories of racial differences. Focuses on some of the racial extremists, including one lecturer espousing fertility controls on nonwhites. (SLD)

This study compared maladaptive behavior in 23 people with Prader-Willi syndrome due to paternal deletion and in 23 age- and gender-matched subjects with maternal uniparental disomy. Controlling for IQs, the deletion cases showed significantly higher maladaptive ratings, more symptom-related distress, and more behavior problems. Findings suggest a…

A survey of the families of 62 persons with Prader-Willi syndrome examined the prevalence, topographies, and specific body locations of self-injurious behaviors. Self-injury was reported for 81% of the participants. Skin-picking was the most prevalent form with the front of the legs and head being disproportionately targeted. Incidence also varied…

Explores the use of "Journal Citation Reports" (JCR) for journal management in academic libraries. Outlines the advantages and disadvantages of using JCR citation data and researches the impact of journal self-citation on JCR rankings of library and information science and genetics journals. (Contains 41 references.) (Author/LRW)

Describes a genetic engineering project to build an intelligent mouse. Cites understanding the molecular basis of learning and memory as a very important step. Concludes that while science will never create a genius mouse that plays the stock market, it can turn a mouse into a quick learner with a better memory. (YDS)

Examines the knowledge that secondary school students have concerning some basic aspects related to the location of inheritance information before they are taught about genetics. Discusses the effects of traditional instruction in Spain on students' learning. (Author/CCM)
