Geniverse vs Virtual Genetics Lab II

Geniverse was free, web-based software for learning heredity and genetics by breeding and studying virtual dragons. Its interactive models used real genes to support simulated experiments and generate genetic data. Dragon genes and traits were based on anole lizards, mice and fruit flies. Activities covered heredity and genetic diseases, asking students to produce evidence and present findings through writing and classroom scientific argumentation. Teachers were expected to guide the work and connect it with real-world genetics. The project described audiences across middle school, high school, higher education and informal learning, with high school biology as its stated focus. Concord reported effects on science knowledge and evidence-based argumentation, while noting classroom implementation influenced outcomes and only 25% of students in one study reached the minimum level. Geniverse has been retired because it became too difficult to maintain after National Science Foundation funding ended. Its Lab resource ran in a browser, including listed Chrome, Safari, Firefox, Internet Explorer and Edge versions.

Virtual Genetics Lab II (VGLII) is a free simulation for students exploring how traits are inherited. Students cross hypothetical creatures and examine offspring, using problems that cover one to three genes. Traits can be autosomal or sex-linked, with simple dominance, co-dominance, or incomplete dominance; instructors can restrict which models are available. Model Builder lets students enter and save genetic models, and instructors can compare responses with correct answers for grading. Version 3 includes chi-squared calculations in the Summary Chart, epistasis and complementation models, and Super Crosses of up to 2,000 offspring. Desktop downloads are listed for Windows, Mac OS X, and Linux/UNIX, and the download page says VGLII requires Java 7 or higher. The maker also describes jsVGL, a browser-based version that does not use Java and can load and save work. The maker says VGLII will no longer be supported, while support will continue for jsVGL. Some macOS versions may show an error about loading the Java Runtime Environment; a workaround uses the app's VGLII.jar file.
