Reviews the rationale for the practice of Artificial Insemination Donor (AID) practices, the manner whereby donors are selected, and how records are kept. The importance of developing standards which serve the best interests of the AID child is stressed. (Author/DB)

A series of environmental-genetical analyses of the left-handedness of 1,950 college students indicates that left-handedness is familial: it is more frequent in families in which at least one parent is left-handed. (Author/CM)

The problem of counseling is dealt with mainly in the context of severe hearing impairment, since moderate forms are often due to illness or other nongenetic factors and do not constitute a grave handicap. (DLS)

Summarizes events of a conference on evolutionary biology in Chicago entitled: "Macroevolution." Reviews the theory of modern synthesis, a term used to explain Darwinism in terms of population biology and genetics. Issues presented at the conference are discussed in detail. (CS)

A sample run is given of a BASIC program used to determine possible genetic characteristics of offspring of parents with known genetic characteristics. (MK)

Data are presented from families of monozygotic twin pairs which give evidence of genetic variance on the Block Design Test, a nonverbal measure of intelligence. Analyses of genetic and environmental effects on behavior are possible with this kind of information. (SA)

Views the discipline of psychology historically with specific concern for its relationship to man's quest for freedom. (Author/RK)

Presents the views of a prominent molecular biologist regarding recombinant DNA research. Contained are arguments for continuing research and a reassurance that the potential hazards from this type of research are overstressed. (CS)

Describes biological influences on criminality. Illustrative data suggest a biological sex difference in criminality and heritable differences in this trait among individuals. Methods of isolating environmental influences are described. Author notes that using environment-friendly behavior genetic research designs is not only proper but would…

Comparison of twins (40 identical and 23 fraternal) for mathematics deficits (MD), in which at least one member had a mathematics disability, found evidence for a significant genetic etiology. However, tests for the differential etiology of MD as a function of reading performance level were nonsignificant. (Author/DB)

Describes a DNA fingerprinting simulation that uses vegetable food coloring and plastic food containers instead of DNA and expensive gel electrophoresis chambers. Allows students to decipher unknown combinations of dyes in a method similar to that used to decipher samples of DNA in DNA fingerprint techniques. (JRH)

Presents a genetics simulation that uses a noncomputer version of BioQUEST's Genetics Construction Kit. Provides students with opportunities for solving realistic genetics problems and allows them to experience how classical geneticists think. Discusses the problem's search space, thinking qualitatively, hypothesis generation and testing, thinking…

Examines whether risk to offspring of developing reading disorders (RD) was dependent on the parents' successful or unsuccessful compensation for their own childhood reading problems. Analyzes two large family data sets. Shows that having at least one still-affected parent put the offspring at a higher risk for RD than having at least one…

Explores the meaning of DNA. Discusses histories of DNA, literature on DNA, the contributions of Max Delbruck and Barbara McClintock, life, views of control, current research, and the language of DNA. Contains 24 references. (JRH)

Describes an activity that combines Mendel's Postulates with Morgan's Chromosome theory of inheritance. Students pair up the mother's and father's genes and learn how the genes line up with each other. Background information on the theories is provided and tips that can be used to aid student understanding are included. (DDR)
