The inclusion of Watson's "The Double Helix" in a high school biology DNA unit is described. (BB)

The special issue presents a collection of 10 studies presented at a major workshop on Usher's Syndrome (a condition of congenital deafness accompanied by progressive loss of vision) which was sponsored by the South Central Regional Center for Deaf-blind Children in Dallas, Texas, September, 1977. (IM)

The purpose of this paper is to isolate the historical and philosophical treatment of genetics in school and college curricula. To do this, a qualitative analysis was made of 128 biology textbooks or textbook series published between the years 1907 and 1977. The results of this study are reported. (Author/MA)

Describes knowledge and attitudes regarding human genetics and biology among a sample of high school students. Also describes how the tests they use serve their interests in these two topics. (BB)

The results reported were obtained from surveys of high school and college teachers conducted in the spring of 1977. (BB)

Included are a discussion, comments, suggestions, and a list of audiovisual materials related to human genetics. (BB)

The principles of modern genetics are extended to study the extinction probabilities of such genetic diseases as sickle-cell anemia, Tay-Sachs disease, and cystic fibrosis. (JT)

Using a very simple computer program written in BASIC, a very large number of random-generated DNA or RNA sequences are obtained. Students use these sequences to predict complementary sequences and translational products, evaluate base compositions, determine frequencies of particular triplet codons, and suggest possible secondary structures.…

The incidence of recurrent mongolism was analyzed among, 2,331 mongol propositi (and their 6,225 sibs) in 34 British institutions and daycare centers. (BB)

A parent-offspring adoption path model, with a measured index of the home environment, was developed to assess extent to which genetic and environmental influences of the parents affect relationships between the environmental index and children's behavior. Intelligence Quotient (IQ) data from the Colorado Adoption Project were used. The…

The study examined preference for social gaze, percentage occurrence of social gaze, nonverbal social avoidance, and nonverbal repetitive behaviors. Prepubertal males with the fragile X syndrome (N=12) demonstrated a higher overall percentage of avoidance for both parent and strangers than handicapped (autistic and Down Syndrome) and…

The present study points out problems in the model, indices of familiality, and design used by Benbow, Zonderman, and Stanley in a study of precocious children and their parents. (Author/LMO)
