AP Lab 2 Evolution

This lab contained a simulation.  We ran the simulation as a group.  Since the simulation was very confusing and they were not following it very well, we simply ran 200 cycles with the preprogrammed mutation rates.  This is just enough information to answer analysis question 1.

The following information is provided if the students want to run it again on their own and further complete the lab with the correct data and graphs.

In genetics, the mutation rate is a measure of the rate at which various types of mutations occur over time.

A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people.

Selective strength is how strong the environment is pressuring evolution. If the difference of survival rate between two versions of a gene is small then it is not a strong selective force, if there is a large survival difference then the selective force is strong.
