Simbiotiks vs StarGenetics

Simbiotiks provides three interactive 3D biology atlases for undergraduate study: an animal cell, the human body, and E. coli. Each atlas offers Explore and Study modes, full nomenclature, and three reading depths; Study mode adds supporting papers. The cell atlas covers nine structures and includes narration. The body atlas presents six anatomical layers, and its page says a female model is coming soon. The E. coli atlas covers eight structures, identifies strain K-12 MG1655, and lists narration as coming soon. All three atlases run in a modern browser without installation. The site lists English, Spanish, Chinese, and Persian. Simbiotiks describes the resources as intended for undergraduate biology and biomedical science, with university-level learners as the primary audience. It says on-screen claims are checked against reference material before release and credits BodyParts3D, Z-Anatomy, and HuBMAP sources for anatomy. Students receive free access without an account; instructors can contact the maker about course content.

StarGenetics is a free simulator for Mendelian genetics crosses, intended to teach genetics concepts and experimental design. Its stated audience ranges from high school biology to advanced undergraduate biology. Students can use visualizers for cows, fish, flies, peas, a smiley face and yeast. Instructor resources cover genetic crosses, Punnett squares, complementation, epistasis, gene linkage and mapping, and tetrad analysis. Instructors can customize exercises using Excel workbooks in XLS format. The Punnett Square tool summarizes expected genotypic distributions for monohybrid and dihybrid crosses. Fly mating results can be viewed individually, sorted by sex and phenotype, or summarized by phenotype; DNA markers for genetic mapping are available in the Fly and Fish visualizers. Experiments can be saved to a file and reopened later. Excel export is limited to Fly exercises. StarGenetics is accessible through the web and downloadable for Linux, Windows and macOS. MIT recommends Java Web Start and provides operating-system downloads for users with limited internet connectivity. Users can submit bug reports, feature requests, comments or questions through the in-app suggestions form.
