Describes an exercise in which senior high school biology students used a computer to simulate genetic mapping. The exercise was designed to enhance the students' grasp of the concepts of linkage and crossing-over. (JR)

Discusses the effects of radioactive wastes on marine communities, with particular reference to the fitness of populations and the need for field and laboratory studies to provide evidence of ecological change. (JR)

Comparing group intelligence according to racial or geographic orgin has neither social nor scientific value; the emphasis in education and the social economy is not the creation of equality but the development of each individual to his maximum performance. (Author/JM)

Presents a review of genetic engineering, in which the genotypes of plants and animals (including human genotypes) may be manipulated for the benefit of the human species. Discusses associated problems and solutions and provides an extensive bibliography of literature relating to genetic engineering. (JR)

Discusses the curriculum of "Introduction to Genetics" of the Unitversity of Freiburg, West Germany. (DD)

Insecticides should not be the only weapons of war used against pests; in addition to them, a strategy aimed at winning the millenial warfare should combine the tactical use of natural plant enemies, reinforced plant genetic qualities, and the application of adequate ecological techniques. (BL)

Describes a high school biology exercise in which a computer greatly reduces time spent on calculations. Genetic equilibrium demonstrated by the Hardy-Weinberg principle and the subsequent effects of violating any of its premises are more readily understood when frequencies of alleles through many generations are calculated by the computer.

That residents of Papago villages were less closely related in the 19th century than during recent decades is considered in historical and genetic perspectives. A preliminary version of this paper was read at the annual meeting of the American Anthropological Association, New York City, 1971. (FF)
