    Abstract

    This thesis extends the use of the single-celled alga Chlamydomonas reinhardtii as a model organism for understanding the evolution of both sexual reproduction and anisogamy. I discuss the potential utility of the Environmental Threshold Model in understanding the evolution of sexual reproduction, and describe novel methods for testing the assumptions underlying this model. New methods for the artificial selection of gametes based on cell size or cell speed are introduced, and selective disruption of populations based on cell motility is used to demonstrate the positive relationship between cell size and speed in this species.
