Rosalind vs StarGenetics

Rosalind is a free web learning platform that teaches bioinformatics and programming through problem solving. Its tracks include Python Village, Bioinformatics Stronghold, Bioinformatics Armory, Bioinformatics Textbook Track, and Algorithmic Heights. Python Village introduces programming basics, while Stronghold covers mass spectrometry, sequence alignment, genome assembly, phylogeny, probability, and string algorithms. Submissions are checked automatically. Learners may code on their own computers and upload or paste answers, using any programming language. Rosalind targets biologists developing programming skills and programmers new to computational molecular-biology problems. Faculty can create classes, assign problems, monitor progress, review submissions, and use a grade sheet; Faculty accounts are free. Problems impose time limits and waiting after incorrect answers. The Faculty page says plagiarism checking was being implemented, requiring instructors to compare code themselves meanwhile. Public access costs nothing.

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.
