This article reviews research regarding the effect of heredity on athletic performance. Research on twins indicates that genetic makeup may have a strong role in aerobic capacity, adaptability to training, composition of muscle tissue, and personality traits relating to competitiveness and leadership.

Of 51 Louisiana students with Usher's Syndrome (a genetic condition characterized by hearing loss and progressive blindness), 71 percent manifested visual impairment and hearing loss, 9 percent had neither, 10 percent had visual impairments but a less-than-profound hearing loss, and 10 percent had profound hearing loss and no visual impairment.…

Reviews much of what is known about microtubules, which are biopolymers consisting predominantly of subunits of the globular protein, tubulin. Describes the functions of microtubules, their structure and assembly, microtube associated proteins, and microtubule-disrupting agents. (TW)

Describes (in separate articles) 25 developments in science, technology, and medicine that have potential impact on the near future. They include discoveries related to space butterflies, drugs, twenty-first century software, experimental mathematics, brain drugs, egg development, ultrasmall microchips, the biology of birth, cancer-causing genes,…

Discusses the conditions for validating customary phylogenetic procedures. Concludes that the requisites of homogeneity and completeness for proved short lineages seem satisfied by the Hennigian but not the Haeckelian procedure. The epistemological antinomy of the two procedures is emphasized for the first time. (Author/RH)

Suggests activities designed to introduce elementary school students to the idea of inherited traits. Discusses dominant and recessive genes, genotypes and phenotypes, and such traits as attached earlobes, tongue-rolling, and widow's peak. (DH)

Provides background information for teachers on the physical and physiological characteristics of fruit flies. Explains their role and function in the study of heredity. Upholds their value as a manageable and safe laboratory animal. (ML)

Provides: (1) a glossary of terms used in biochemical engineering; (2) a list of key developments in the field; and (3) emphases placed in 15 topic areas in a course restructured on the basis of these developments. Topic areas include enzyme kinetics/applications, genetics and microbial control, transport phenomena, and others. (JN)

Describes an exercise in biometrical genetics based on the noninteractive use of a computer simulation of a wheat hydridization program. Advantages of using the material in this way are also discussed. (Author/JN)

Primary prevention, as applied to the children of psychotics, should be directed against the transmission of psychosis to the next generation of adults and toward the relief of psychopathology in the children. It should be remembered that genetic and environmental factors interact in the etiology of mental illness. (Author/CMG)

Discusses the sampling and data-collection techniques used to study the heights, intelligence levels, and aggression levels of XYY and XXY males. (MLH)

Attempts to emphasize some of the rather precise analytic and predictive values of evolutionary theory, applied to parental behavior. (Author/RK)

The response that this generation and the next generation gives to that most basic question of all, "What is man?," was the focus of this article. It attempted to make us aware of and informed of the topic. (Author/RK)

Presented is a case study of a family in which a pair of twins have epiloia (characterized by epilepsy, abnormal skin pigmentation, and severe mental retardation). (DB)

Retinitis Pigmentosa includes a number of inherited diseases which usually result in blindness. The disease is progressive in nature and begins with the deterioration of cells in the eye responsible for peripheral vision. As the condition worsens there is a gradual loss of peripheral vision and night blindness. Proper educational planning requires…
