Hardy Weinberg and the Pocket Mouse


In this activity, students use real world data on the color distribution of rock pocket mice to show that evolution has occurred using the Hardy-Weinberg equation, which states that allele frequencies will change over time as a result of evolution.

This activity can be included in a longer study on rock pocket mice that can be accessed at BioInteractive, where students can also watch a short video about the research on these desert mice.

The worksheet is intended to be assigned after students have been introduced to the Hardy Weinberg equation and have done some of the practice problems.
