This module does a good job of explaining the basics of how to use a Punnett square to diagram dihybrid crosses. Example crosses are solved step-by-step at a relatively slow pace. This activity would be best for students who are learning about the basics of genetics for the first time, and would probably be boring to more advanced students. Although the interface is somewhat aesthetically unappealing, the content does a good job at teaching the student how to use Punnett squares.
I am reviewing this resource as a former Genetics TA - I recall students struggling to understand the statistics underlying parental crosses and I want resources that could help students move from drawing Punnett squares to calculating the ratios using probabilities. Here I provide a close description of the technology in this resource. While 10 of the 11 pages of this module are free, easy to view, and run via a web browser, there is one page with a Java applet. Unfortunately, I have Java disabled on my computer due to security issues associated with Java. Therefore, I could not use the applet, although it sounded really cool!
