The focus of the Association for Biology Laboratory Education (ABLE) is to improve the undergraduate biology laboratory experience by promoting the development and dissemination of interesting, innovative, and reliable laboratory exercises. This proceedings volume contains 17 papers on the topics of cell and molecular biology, genetics, and development; physiology; and evolution, ecology, and behavior: "A Study of Gene Linkage and Mapping Using Tetrad Analysis in the Fungus 'Sordaria fimicola'" (J. C. Glase); "A Holistic Approach to Teaching a Laboratory, Using Sea Urchin Development as an Example System" (A. Eisen); "Human Chromosome Analysis" (C. C. Tseng); "Sister Chromatid Differentiation and Exchange in Chinese Hamster Ovary Cells in Culture" (J. C. Tan); "Measurement of Photosynthetic Activity in Plant Cell Fractions" (N. Scott & B. Greenberg); "Diversity of Photosynthetic Pigments" (A. F. Motten); "Carbon Dioxide Uptake in Plants: A Computer-Aided Experimental System" (C. J. Paradise & R. J. Cyr); "Developmental Plasticity in Oak Leaves" (D. Westmoreland); "Pollen Tube Formation and the Central Dogma of Biology" (R. J. Scott); "Immunocytochemical Analysis of Sperm Cytoskeleton" (B.
