Assignment of lab
In this lab you’ll explore the concept of microevolution by collecting and analyzing data from real populations. It is similar in some ways to the Mendelian Genetics lab, but instead of tracking traits at the individual/family level, you’ll be doing so at the population level.
the lab assignment document with questions for you to answer
a spreadsheet that you will use to record your data
the ‘Statistics In Introductory Biology’ reference document that you’ve used before
