Go to the Sexual Selection Simulation on Biology Simulations

1. Read through the text at the beginning of the simulation and the text in the introduction.

2. Experimental Question: When brighter males are more likely to mate but are also more susceptible to predation (getting eaten by a predator), how will the level of predation pressure affect the coloration of the male population?

Write a hypothesis:

As the pressure of predation increases, the population of brighter males will decrease.

3. Select a starting percentage for bright males and a number of generations. This will stay the same throughout the experiment.

Starting % Bright:

50%

Generations:

70

Continue onto the next page to record your data

4. Select 5 different predation pressure levels and run the simulation 3 times for each. Record your

data (final male coloration frequencies) below.

Remember, the coloration frequency x 100 represents the percent of the population that is that color. It will never be greater than .5 (or 50%) because this is just the males. The other .5 (or 50%) are female.

5. Conclusion: What did the results tell you? Was your hypothesis proven correct, incorrect, or do you need more data? Why do you think the results are what they are?

My hypothesis was correct and as the pressure of predators increases, the population or bright colored men decreases because they are eaten by more predators.

6. Compare your results to the other students in your group. Did the starting % or number of generations chosen make a difference to the results? Explain. *If your table is not done or you are at home, you can run the simulation a few times with significantly different numbers of generations to get an idea of how the results might be different.

Yes, because as time goes on more predators will come to that ecosystem or leave

7. Research, describe, and explain in your own words a real-life example of intersexual selection.

An example of a real-life example of intersexual selection occurs in peacocks, the maales will spread their feathers to attract the females.
