This is an activity for introduction to meiosis. It goes with the site http://www.biology.arizona.edu/cell_bio/tutorials/meiosis/main.html. The students should have some foundation in mitosis, as this builds upon those concepts. There is not a key, but there is value in completing the activity. It is computer based, and can fit into the category of "webquest." I typically have the students start this after they complete the mitosis quiz.
