Intended for use by the public as well as by medical professionals and related service agencies, the booklet presents genetic counseling as a means of providing information to deal with genetic disorders in general and mongolism (Down's syndrome) in particular. Characteristics of mongolism and possible emotional effects on the family of a…

Most of the activities suggested in this trial version of the Genetics unit produced by the Australian Science Education Project rely on second-hand data, although one of the introductory activities suggested is based on results of a mouse breeding experiment. The unit is, therefore, expected to be suitable only for students who are capable of…

Investigates the possible relationships between the ability of introductory college genetics students to perform Piagetian formal operational tasks and their ability to solve problems requiring genetic analysis. (Author/GA)

Social and ethical issues are examined in relationship to life management practices with the profoundly retarded. (Author)

The article provides a detailed and critical review of the book, "The Neuropsychology of Learning Disorders" (1976), edited by R. Knights and D. Bakker. (Author/SBH)

Investigated high and low entering behavior levels and different cognitive levels of behavioral objectives across four treatments. Findings indicated that preassessment of student knowledge is a useful educational tool and that educators should be cognizant of learning variables that interact in the learning process so that unfounded…

Discusses the importance of and need for genetics education for both medical professionals and the public. The nature nurture controversy is included in terms of environmental conditions causing the expression of certain genetic predispositions. (MA)

The broad area of biochemistry is surveyed. Subtopics include nuclei acids, peptide hormones, cell surfaces, and enzymology. (MDR)

In this review educational researchers are apprised of some potentially important developments in evolutionary biology. The field is outlined as it is spelled out in two recent books on sociobiology and behavior. The relationship between the two areas is discussed. (Author/GC)

A twin-based analysis of personality inventory scales yields information relevant to construct validity. Criteria for construct validity derived from adolescent twin statistics are illustrated with Wiggins' MMPI Content Scales. A type of discriminant validity indicates that some scales are not distinct in terms of influences of familial…

A sample run of a program intended for use by students with access to a teletype or visual display computer is shown. The program is satisfactory for the testing of the law for up to about 20 generations using any valid set of frequencies for genotypes. (AJ)

The special problems and implications associated with genetic screening of blacks in the U.S. are discussed. (Author/AM)

Reviewed are advances in the past century in cellular genetics. (CL)

Presents current findings and theories on the causes of Down Syndrome. Reviews research which focused on chromosome 21 and the pathologies associated with it. (ML)

Explains an experiment in which the rotation of a patch of skin on a tadpole results in a frog with rotated spots, proving that the spot pattern is determined long before it becomes visible. Procedures used are included. (DH)
