Studied hand skill and performance in children (N=115) of left-handed parents using peg moving tasks and soccer kicks. Concluded that being raised by two left-handed parents does little to hinder the expression of the rs plus gene. Correlations for handedness in families depend more on genetics than experience.

The author views various historical incidents of importance to present world trends and predicts a few more for the future. He also urges industrial arts teachers to encourage students to take the long-range view of society and determine what role they wish to play in it. (CT)

Discusses biotechnology in terms of its potential and the bottlenecks encountered in the course of development. Topics/issues addressed include: biotechnology definitions; research prospects; raw material constraints; co-ordination/financial support; training; industry/university conflicts; possible risks; and legal protection involving living…

Describes a rapid staining technique for investigating the anatomical expression of two recessive genes. The demonstration is intended to stimulate students who are interested in the practical applications of genetics. (Author/SA)

Discusses the increasing significance of genetic diseases and defects in our lives and the social, moral-ethical, and legal problems resulting from medical genetics. (Author/SA)

Discusses implications of recent evidence for genetic influences on personality development and psychopathology. Presents a model of the childhood origins of psychopathology that incorporates genetics and gives special emphasis to the role of parental conflict in the previously neglected middle childhood years. (Author/GC)

Discusses questions dealing with genetic aspects of the correlation between IQ and socioeconomic status (SES). Questions include: How does assortative mating affect the genetic variance of IQ? Is the relationship between an individual's IQ and adult SES a causal one? And how can IQ research improve schools and schooling? (Author/DB)

Describes how plants can be produced by cloning by using tissue culture methods to mass-produce rare native prairie plants and trying to transfer some of the genetic characteristics of native grasses into cultivated cereals. The experiment was conducted at South Dakota State University. (HM)

Describes a game that illustrates the principles of population genetics and helps explain the occurrence of evolution through changes in gene frequencies. Demonstrates the importance of genetic variability in evolution: winning is achieved by a player's species becoming "completely heterozygous" for six characteristics. Players move directed by…

Details the construction of a viewing chamber for fruit flies that connects to a dissecting microscope and features a design that enables students to easily move fruit flies in and out of the chamber. (DDR)

Describes an approach to a course about the basics of genetics and molecular biology that utilizes a contest that involves students in accessing information about a topic such as sex determination, neural development, and gene therapy. The general objective of the approach is to inspire students to become familiar with the scientific literature.…

Describes an intelligent Web-based construction project management system called VHBuild.com which integrates project management, knowledge management, and artificial intelligence technologies. Highlights include an information flow model; time-cost optimization based on genetic algorithms; rule-based drawing interpretation; and a case-based…

Examined data from 408 pairs of identical, same-sex fraternal twins at 14, 20, and 24 months to assess cognitive development and to identify genetic and environmental influences on phenotypic similarity. Found various patterns of development for separate constructs, for females versus males on each construct, and for individuals across constructs.…
