This is something we will discuss in class - do not complete this until we discuss it!
Post Activity Questions: the first question on this assignment refers to the tables in the procedure document. You have to complete those tables in order to receive credit for that question. You don't need to show your work anywhere.
3

Did you fill out tables 1-5 in the lab procedure document? (this answer will be graded based on whether your answers on those tables are correct) Remember - you don't need to show your work just fill in the tables.

0.25

In simulation 1 (the experiment without selective pressure) what happened to the frequency of the dominant (p) and recessive (q) alleles over the 5 generations?

0.25

What type (if any) of natural selection occurred in simulation 1?

0.25

In simulation 2 (the experiment with selective pressure against blue) what happened to the frequency of the dominant (p) and recessive (q) alleles over the 5 generations?

0.25

What type (if any) of natural selection occurred in simulation 2?

0.25

In simulation 3 (the experiment with selective pressure against red) what happened to the frequency of the dominant (p) and recessive (q) alleles over the 5 generations?

0.25

What type (if any) of natural selection occurred in simulation 3?

3.25

Compare your answers to the previous questions and explain why you think the frequencies changed differently in the first 3 simulations. This should be a longer answer and include significant vocabulary and detail. You aren't talking about simulation 4 yet.

0.25

In simulation 4 (the experiment with the toxic waste dump) what happened to the frequency of the dominant (p) and recessive (q) alleles over the 2 generations?

0.5

Natural selection did not occur in this simulation even though the frequency of the fish color changed. Instead, what other type of microevolution happened in simulation 4?

1.5

How do you know what type of microevolution occurred here? Why do you think this isn't an example of directional selection even though the frequency of one of the extremes increased? (This doesn't need to be as long as the free response about the first 3 simulations, but it should include solid vocabulary and detail)
