COSM

Meiosis Models

Activity Summary
In this lesson, students use a variety of candy (licorice, gummy worms, gummy bears, etc.) to model the replication and division of chromosomes during sexual cell division (meiosis). While doing so, students examine how meiosis increases the diversity of populations.
