CAROLINA LABSHEETS
In this lab, students investigate how the events of meiosis relate to Mendelian genetics. The lab is designed to supplement the Meiosis Activity of our Carolina BioKits ® : Chromosome Simulation.
Small, colored adhesive dots can be used in place of the masking tape from the kit.
Students use a model of chromosomes, featuring simple-to-manipulate pop beads and magnetic centromeres, to understand and model the phases of mitosis and meiosis.
Ensure that students understand and adhere to safe laboratory practices when performing any activity in the classroom or lab. Demonstrate the protocol for correctly using the instruments and materials necessary to complete the activities, and emphasize the importance of proper usage. Use personal protective equipment such as safety glasses or goggles, gloves, and aprons when appropriate. Model proper laboratory safety practices for your students and require them to adhere to all laboratory safety rules.
Students may work individually or in groups of two or more.
Before students perform this lab, ensure they have completed the Mitosis and Meiosis Activities of Carolina BioKits® : Chromosome Simulation so that they know how to assemble the chromosome bead models and simulate the events of cell division. They need the Student Guide for the Meiosis Activity on hand to use as a reference.
If students begin this activity immediately after finishing the Meiosis Activity, they can work with the materials they already have; otherwise, they will need to get the following items from the kit:
Optional: Students may combine their groups and simulate a dihybrid cross. This will illustrate independent assortment and will probably bring up the question of what happens to genes on the same chromosome (linkage).
