After the rediscovery of Mendel's laws of heredity in 1900, the biologists who began studying heredity, variation, and evolution using the new Mendelian methodology--performing controlled hybrid crosses and statistically analyzing progeny to note the factorial basis of characters--made great progress. By 1910, the validity of Mendelism was…

For the past two centuries deaf people in the United States have faced more or less intense skepticism about their marriages to each other, largely due to fears of inherited deafness. These fears, while always present, have waxed and waned over time, becoming most prominent during the eugenics era of the late nineteenth and early twentieth…

The International Conference on Academic Studies in Technology and Education (ICASTE) is set to take place at Amara Premier Palace Hotel in Antalya, Turkey, from November 16-19, 2023. Organized by the International Society for Research in Education and Science (ISRES) and the International Society for Academic Research in Science, Technology, and…

Podcasts are audio or video files which can be automatically downloaded to one's computer when the episodes become available, then later transferred to a portable player for listening. The technology thereby enables the user to listen to and/or watch the content anywhere at any time. Formerly popular as radio shows, podcasting was rapidly explored…

Makes the case that, contrary to popular belief, Mendel's famous paper about plant breeding announced no major findings. Reports on the paper's rediscovery as a result of a priority dispute between de Vries and Correns. (Author/MM)

The use of a computer program to provide a simulated genetics laboratory for students in an introductory course in genetics is described. (Author)

Compares identical and fraternal twins to determine if communicator style is inherited. Finds predictable relationships between Temperament and Communicator Style, with identical twins' scores more closely related than fraternal twins' scores on nearly every variable studied. (SR)

Discusses genetics and heredity and their relation to human behavior. (JRH)

Gangestad and Snyder (1985) have proposed two types of personality variables: continuous variables (characteristics possessed to some degree by all individuals) and class variables (characteristics distributed into discrete classes). This study examined whether alcoholism could be classified as a class variable. Because a class variable will…

Examines 21 recent introductory psychology textbooks to determine their treatment of A. R. Jensen and his theory of intelligence. Findings show that Jensenism is still an issue but that the trend is toward implicit or explicit rejection of the Jensen hypothesis. (CK)

Presents four misconceptions students have concerning the concepts of recessive and dominant alleles. Discusses the spectrum of dominant-recessive relationships, different levels of analysis between phenotype and genotype, possible causes of dominance, and an example involving wrinkled peas. (MDH)

Describes the successful use of giving examples of genes affecting various steps in biochemical pathways to teach gene interaction. Finds that once students grasp the notion that genes can interact because they control different steps within biochemical pathways, the reason why phenotypic ratios appear to be non-Mendelian becomes more obvious and…

Provides a comprehensive contemporary summary of the world literature on IQ correlations between relatives. A profile of average correlations consistent with a polygenic mode of inheritence is revealed from a summary of 111 studies, although a marked degree of heterogeneity of the correlations within familial groupings is also found. (CS)

Discusses whether the discovery in 1956 that humans have a chromosome number of 46, as opposed to 47 or 48 as previously thought, fits into a paradigm shift of the Kuhnian type. Concludes that Kuhn probably would not have considered the chromosome number shift to be large enough to be a focus for one of his paradigms. (AIM)
