ACTIVITY #1: KOI EVOLUTION
A population that is under the Hardy-Weinberg equilibrium will remain genetically stable over time. This
will happen if none of the assumptions of the Hardy-Weinberg equilibrium are violated. In this activity
we will start with a stable population of Koi fish that are under Hardy-Weinberg equilibrium. We will
then manipulate specific variables in an attempt to violate certain assumptions of the Hardy-Weinberg
equilibrium to see what affect it has on the population.
The simulation is located here:

Before you being the activity questions below, go through the “Background Information” for an
overview of evolution and Koi breeding and the “Tutorial” for an explanation on the layout and options
in the simulation. The select “Run Experiments”.
The simulation will start with a population under Hardy-Weinberg equilibrium. The population remains
stable even at the allele level. Allow the model to run with the default settings for 200 generations. You
can manipulate the speed go it was run faster.
1. Record the final population size, proportion for the R allele and the r allele.
2. Looking at your Allele Proportion graph, give a one sentence summary of the change in allele
proportion over time.
You will now violate one of the assumptions of the Hardy-Weinberg equilibrium and see what affect that
has on your population. Select the “Re-set” button to re-set your data and choose ONE of the following
variables to change: Migration or Mutation Rate. You can adjust any, or both, of the options under your
variable of choice and then run the model for 200 generations.
3.List the variable (Migration or Mutation Rate) that you chose and give the levels chosen for both
options within your variable.
4. Record the final population size, proportion for the R allele and the r allele.
5. Comparing these results to the results of the default model give a 2-3 sentence summary of what has Changed.
