1. Some of the organisms that are used as highly informative models to study gene action and development. (a) Escherichia coli is a common bacterium; (b) Saccharomyces cerevisiae is a yeast; (c) the fruit fly Drosophila melanogaster and (d) Caenorhabditis elegans, a nematode, allow sophisticated studies of comparatively simple animal body plans; (e) Danio rerio, the zebrafish, and (f) Mus musculus, the laboratory mouse, represent more complex vertebrate model systems; (g) Arabidopsis was one of the first plant model organisms in genome projects.
