Reviews a software package, "Mitosis-Meiosis," available for Apple II or IBM computers with colorgraphics capabilities. Describes the documentation, presentation and flexibility of the program. Rates the program based on graphics and usability in a biology classroom. (CW)

Presents an algorithm for solving problems related to multiple allelic frequencies in populations at equilibrium. Considers sample problems and provides their solution using this tabular algorithm. (CW)

Recent data suggest that genes influence three domains of great importance to family researchers: (1) developmental outcomes; (2) family variables that are thought to influence those outcomes; and (3) covariance between measures of family process and developmental outcomes. Influence of genes on variances and covariances challenges current…

Using socks with colored bands, a teacher makes mitosis and meiosis fun and meaningful for students.

Reviews the behavioral, cognitive, and other psychological features of Prader-Willi Syndrome (PWS), exploring their relationships to known genetic mechanisms. PWS is a genetic developmental disability characterized by a group of specific behavioral features, including an insatiable appetite. The article briefly touches on PWS-related research at…

Knowledge about the inheritance of breast cancer and attitudes about genetic testing for breast-ovarian cancer susceptibility in women at increased risk were studied in Caucasian and African-American women (N=407). Participants had at least one first-degree relative with cancer. Differences in knowledge and attitudes toward risk may be attributed…

Presents a diminutive overview of research and a case study of Beckwith-Wiedemann syndrome (BWS), a rare, genetically complex congenital disorder. Prenatal diagnosis of this case included omphalocele, hydonephrosis, and possible horseshoe kidney, detected by ultrasound. The characteristics of this disability and related problems are discussed.…

Ten myths and countermyths about intelligence are explored. It is argued that the desire for simplicity and publicity has led psychologists and others writing about intelligence to take positions that cannot be justified by current theory or recent data. However defined, intelligence is but one aspect of being human. (SLD)
