Fish Activity (Hardy-Weinberg) 2023 - 2024 - Kate Turner | Biblioteka

This is something we will discuss in class - do not complete this until we discuss it!

This is a red assignment meaning you should not be using AI at any point while completing or reviewing this assignment.

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 on the lab procedure document (the last page)? (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. You should hand in a hard copy of this document.

Yes!

No - I'll go back to the document and do that now

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? I would compare how much yours changed to the other simulations and if it didn't change as much as the others I would say they stayed approximately the same.

The frequency of p increased and the frequency of q decreased

The frequency of q increased and the frequency of p decreased

The frequencies of both p and q stayed approximately the same

0.25

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

Directional selection

Stabilizing selection

Diversifying selection

Natural selection did not occur because there was not a favored trait

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?

The frequency of p increased and the frequency of q decreased

The frequency of q increased and the frequency of p decreased

The frequencies of both p and q stayed approximately the same

0.25

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

Directional selection

Stabilizing selection

Diversifying selection

Natural selection did not occur because there was not a favored trait

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?

The frequency of p increased and the frequency of q decreased

The frequency of q increased and the frequency of p decreased

The frequencies of both p and q stayed approximately the same

0.25

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

Directional selection

Stabilizing selection

Diversifying selection

Natural selection did not occur because there was not a favored trait

4

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

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?

The frequency of p increased and the frequency of q decreased

The frequency of q increased and the frequency of p decreased

The frequencies of both p and q stayed approximately the same

0.25

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?

Genetic Drift (Bottleneck Effect)

Genetic Drift (Founders Effect)

Gene Flow

1

How do you know what type of microevolution occurred here (in simulation 4)? 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 including data)
