StarGenetics is a genetic cross simulator. It aims to simulate real genetics experiments to teach students about genetic experimental design.StarGenetics allows students to simulate mating experiments between organisms that are genetically different across a range of traits to analyze the nature of the traits in question.

Unlike other available online genetic tools, StarGenetics allows for customization of the experiment presented to the student. In StarGenetics, instructors can specify simple to complex genetic interactions, as well as the genotypes, phenotypes and other genetic characteristics of the organisms provided in a particular experiment.
