The porphyrias are a family of genetic disorders whose genetics and biochemistry are largely identified. Background information on these diseases are discussed including porphyrins, gene expression, population genetics, and historical significance. (CW)

Discussed are some of the uncertainties in human genetic mechanisms that are often presented as dogma in Biology textbooks. Presented is a brief historical background and illustrations involving chromosome abnormality in humans and linkage studies in humans. (CW)

Presents a hands-on activity designed to be a simulation of meiosis. (WRM)

Presented are suggestions for using human pedigrees in the classroom and a generic pedigree that can be modified and used by instructors to provide variants for analysis. Eight single-gene mechanisms of inheritance are defined for use in this activity. (CW)

Presented are arguments for the use of a case study approach for the teaching of human heredity. The design of case studies and related exercises is discussed. Five examples are given. A list of eight resources for case study samples is included. (CW)

Compares different views of the role of sexual reproduction concerning the survival and evolution of species. Discusses the benefits and disadvantages of thelytoky, one nontraditional method of reproduction. (CW)

Described is a laboratory experiment that can be used to investigate bacterial survival in soil or water as well as the study of genetic transfer via conjugation. Discussed are materials, laboratory procedures, typical results, and a list of six references. (CW)

An activity in which students transform an ampicillin-sensitive strain of E. coli with a plasmid containing a gene for ampicillin resistance is described. The procedure for the preparation of competent cells and the transformation of competent E. coli is provided. (KR)

Examines the change and general view of methods in biological science and the possible consequences for biology education. States that the transition was from descriptive biology to theoretical biology. Lists the postulates of some theories. (RT)

An activity that introduces students to the concepts of independent assortment of alleles during meiosis and gametogenesis, the richness of the variation that occurs as a result of allele recombination, and the unique phenotypes of offspring. Reproducible handouts with the directions and model chromosomes are provided. (KR)

This curriculum module explores genes, environment, and human behavior. This book provides materials to teach about the nature and methods of studying human behavior, raise some of the ethical and public policy dilemmas emerging from the Human Genome Project, and provide professional development for teachers. An extensive Teacher Background…
