Plant genetics simulation

Developed at the University of Wisconsin-Madison, CGS allows students to perform virtual test crosses with model organisms. Instructors can set the parameters for the populations under study, such as the number and type of traits in a population, the modes of inheritance and trait linkage. Students determine which crosses to perform and interpret the resulting data. CGS can be used as a primary laboratory module for introductory biology or genetics courses, or as a supplement to a hands-on genetics module with real organisms. In addition to mice and Drosophila, test crosses can be performed with Arabidopsis plants using the CGS software. If you do not have an account and would like to explore an example Arabidopsis population for yourself:

Below is a screen capture of an Arabidopsis population being investigated:

Unlike other common model species, Arabidopsis does not contain sex chromosomes, and are self-compatible (a single plant contains both male and female gametophytes and can be crossed with itself). These characteristics, along with a relatively fast life cycle and ease of mutagenesis, have helped to make Arabidopsis the primary model species for the plant research community.
