This is designed as a homework assignment when students are learning about population genetics/ types of natural selection.
Students must first analyze 3 graphs that indicate directional selection, disruptive selection, or stabilizing selection. They then must match those graphs to various definitions and scenarios. Lastly, they must read 5 situations and decide which type of selection the population is exhibiting.
This could also be broken up into two parts and used as bellringers, or simply as classwork.
As always, answer key is included.
