Genetic Drift Lab

$4.99

Students use fruit ring cereal to simulate genetic drift and gene flow in this fun and low-prep genetic drift lab. First, student read background information to review genetic drift, genetic diversity, gene flow, and natural selection and answer pre-lab questions pertaining to the background information. Students will then model and collect data on founder effect, bottleneck effect, and gene flow in their cereal population. To sum things up, students will analyze their collected data and answer post-lab questions. A comprehensive lesson plan and answer key are included!

For this genetic drift lab, all you need for one group or individual is a 1/2 cup of fruit ring cereal (Fruit Loops). You could also sub out colored candies, but I find that cereal is the most cost-effective way to facilitate this lab with many students. You will also need a napkin, paper plate, and cup for each group. You can reuse the plate and cup.

 

In this low-prep lab, the fruit cereal pieces represent fictional Rainbow Rabbits and each color of cereal represents the gene for color. Students simulate genetic drift events and gene flow to see how they impact genetic diversity in their cereal rabbit populations.
