Considers advantages of teaching chromosomal aspects of meiosis before introducing principles of Mendelian genetics. (AL)

Paper presented at the Merrill-Palmer Conference on Research and Teaching of Infant Development, February 13-15, 1970. (JE)

The development of the science of genetics through the confluence of separate theories is surveyed in this essay. An outline of classical genetics is emphasized. Interruptions in the continuity of development and the influence of genetics on the biological sciences and man as a social animal are discussed. (VW)

This history for molecular genetics and its explanation of DNA begins with an analysis of the Golden Jubilee essay papers, 1955. The paper ends stating that the higher nervous system is the one major frontier of biological inquiry which still offers some romance of research. (Author/VW)

Discusses the claims for a brave new world of genetic manipulation" and concludes that if we could agree upon applying genetic (or any other effective) remedies to global problems we probably would need no rescourse to them. Suggests that effective methods of preventing genetic disease are prevention of mutations and detection and…

To examine developmental patterns of and genetic influences on common fears, a 51-item survey was administered to more than 2,600 adolescents and adults, including more than 400 pairs of like-sex twins. Findings suggest significant genetic modulation of developmental patterns in the acquisition and maintenance of some adaptive fears. (Author/RH)

Proposes a theory of development in which experience is directed by genotypes and in which genotypic differences affect phenotypic differences, both directly and through experience, via three kinds of genotype-environment effects. The theory adapts the three kinds of genotype-environment correlations in a developmental model used to explain…

Recent research has shown that Down's syndrome is not exclusively related to older women; in fact, there is some evidence to suggest an increase in incidence among women under 35, as well as an influence of the father's age. Genetic and demographic information may help relieve parents' guilt and anxiety. (CL)

The article describes a study being conducted to explore the hypothesis that genetic and/or congenital factors are etiologically significant in certain persons with the syndrome of autism. Preliminary data suggest a larger than expected number of families with multiple incidence of autism. (Author/DB)
