Reviews observations on domestic animals that have led to the identification of environmental teratogens, and have provided insight into the pathogenesis of congenital defects and genetic diseases in man." (Author/AL)

Presents models that ascribe social behavior, such as altruism and parental sacrifices for the young, to a kind of genetic imperative wherein individuals maximize their genetic contribution to the next generation. (GS)

Provides an overview of basic and applied studies for which primates are appropriate subjects. Summarizes the advantages, limitations, and constraints of using nonhuman primates in research. (RT)

Presents the idea that social systems evolve to increase the genetic fitness of individuals in specific environments. Cites examples of animal behavior and environmental influences that may indicate why different social systems have evolved. (GS)

Presents the viewpoints of a prominent behavioral scientist concerning the role of the environment in the evolution of behavior. (CS)

Discussed are some of the strategies required to try to detect and explain DNA markers that account for small amounts of behavioral variation. Situations in both animal and human behavior are described. The link between molecular biology and behavior is highlighted. (CW)

Discusses the advantages of Xenopus laevis as an experimental animal in the study of embryogenesis in vertebrates. Summarizes the contributions of this system to the analysis of ribosomal and 5S RNA genes, and the diverse and highly productive applications of the oocyte injection technology. (RT)

Discusses advantages of nematode use for studying patterns of cell division, differentiation, and morphogenesis. Describes nematode development. Cites experimental approaches available for genetic studies. Reviews the topics of control of cell division and differentiation, the nervous system, and muscle assembly and function of the organism. (RT)

Discusses the role of the fruit fly in genetics research requiring a multidisciplinary approach. Describes embryological and genetic methods used in the experimental analysis of this organism. Outlines the use of Drosophila in the study of the development and function of the nervous system. (RT)

Describes three methods and their advantages and disadvantages for introducing genes into animals. Discusses the predictability and tissue-specificity of the injected genes. Outlines the applications of transgenic technology for studying gene expression, the early stages of mammalian development, mutations, and the molecular nature of chromosomes.…
