Provided is a microcomputer program listing which demonstrates the effects of selection on gene frequencies. A very brief description of the program is also provided. (JN)

Because many people still believe that specific, identifiable genes dictate the level of human intelligence and that the number/quality of these genes can be evaluated, presents evidence from human genetics (related to nervous system development) to counter this view. Also disputes erroneous assumptions made in "heritability studies" of human…

Among the many theories attempting to explain sex differences in spatial ability, one of the most highly researched is the X-linked recessive gene theory. This is a review of the major research done on that theory and shows the conflicting nature of the results. (Author)

Reasons for studying human genetics are discussed. These include philosophical reasons, reasons of health, and social reasons. While content, interpretation, and emphasis of human genetics study will vary depending upon schools, teachers, and developmental stages of students, it is suggested that teachers address these three domains. (Author/JN)

Information from scientific journals on the biology of skin color is discussed. Major areas addressed include: (1) biology of melanin, melanocytes, and melanosomes; (2) melanosome and human diversity; (3) genetics of skin color; and (4) skin color, geography, and natural selection. (JN)

Results from a human genetics/bioethics needs assessment questionnaire (N = 124 out of 300) mailed to Indiana health teachers are reported. Genetic topics and human genetic diseases/defects included in health science instruction are listed in two tables. Responses to 16 science/society statements (and statements themselves) are also reported. (SK)

Reviews the benefits and hazards of genetic engineering, or "recombinant-DNA" research. Recent federal safety rules issued by NIH which ease the strict prohibitions on recombinant-DNA research are explained. (CS)

Outlines a humanities course which focuses on six topics: medical ethics, nuclear power, genetic engineering, drugs, energy, and cognitive abilities. Course requirements and units are described. (DC)

Researchers of physiological factors resulting in reading disabilities have studied intelligence, prenatal and postnatal influences, sensory factors such as adequate visual, hearing, and tactile functioning, and genetic predetermination. Chronic health problems which cause frequent absences from school can also result in lower achievement. (JN)

This paper presents further evidence to demonstrate the existence of intra-uterine effects within the normal range of intelligence. The argument is then extended further to estimate the effects of organic factors in the environment that are also pathogenic for intelligence. Various implications of these factors are discussed. (Author/KC)

In this "thank-you" letter to Mr. Pascal, many applications for Pascal's triangle are pointed out. (MK)

Focuses on rewards in scientific research. Discusses the social structure of science and its ability to inhibit creativity as ilustrated in the work, "The Act of Creation: Creative Processes in Science." This is related to accounts of the discovery of the chemical structure of DNA. (SA)

Reports on the status of the Recombinant DNA Advisory Committee (RAC) and attempts to rationalize Suburban Highway Policy. Effective communication among members of the RAC is a current problem facing the committee. A federal transportation priority spending policy is suggested during these times of money and fuel shortages. (MA)

Discusses the fact that many food plants derive from domesticated rather than natural strains, and that natural germplasm or genetic strains used in the plant-improvement process must be carefully preserved. (MLH)

Suggests and describes laboratory activities in which the Mexican axolotl (Ambystoma mexicanum Shaw) is used, including experiments in embryology and early development, growth and regeneration, neoteny and metamorphosis, genetics and coloration, anatomy and physiology, and behavior. Discusses care and maintenance of animals. (CS)
