Simulation Activity
To get started, click on the "Simulation" button at the top of the map. Select the severity of different mutations and the size of the two daughter populations, then click "Start" to see frequencies change over time. After you've tried the simulation at least once, click the button below to answer questions showing that you’ve understood the concepts covered here.

You must try the simulation before answering the questions.

Questions

Question 1.1

Click on the "Simulation" button at the top of the interactive figure to switch over to the simulation review. Click "Start" and run the simulation until the parent population splits in two. Click "Stop", reset the simulation, and try again 4 more times.

Question 1.3

Using the following settings, run the simulation four times for 100 generations each:

  • Population size: 50 on both daughter populations
  • Mutations: set all mutant phenotypes on both daughter populations to neutral (except for the black phenotype, which is deleterious by default)
