Evolution: Electronic Lab Notebook
Purpose
Methods/Results^
In order to do the Evolution portion, user will use the program named Aipotu.
Aipotu can be downloaded using this link: Aipotu Home Page
Once link is clicked, user will go to the Download tab, and follow instructions to acquire program.
Part A
- In Greenhouse, user will click on Red and White flowers
- User will click on Load
- User changes fitness of red to 10 and the other flower colors to 0
- Answer prediction question
- Test prediction by clicking on One Generation Only in Controls
Prediction: Overall, after changing the fitness, it can be predicted that red flowers will dominate after several generations with this selection.
Result: After clicking loading, there was a count of 52 red flowers and 48 white flowers. It can be seen that there is roughly a 50:50 ratio between the two colors with a fitness of 5 for each color. Once fitness was changed, the count of the red flowers increased. Therefore, the prediction that was made follows with the results. After loading one generation only, the red flowers count went up to 69 and the white flowers went down to 31. After one generation, white is still visible, but it is the recessive trait in this pool. After 3 simulations, the red flower count increases and the white flower count decreases. By 11 generations, there is a pure red generation. Some all-red generations can have some white offspring because all-red flowers can be considered as homozygous or heterozygous dominant alleles. Therefore, if it is considered heterozygous, then there is a chance that there would be white offspring.
Part B
- Click on Red and White flowers
- Click on Load
- Change Fitness settings for the White flowers by making it 10 and the other colors to 0
- Answer prediction question
- Test by clicking on One Generation Only button
Prediction:
Result:
Part C
- In World settings, click on Preferences
- Click on Show colors of Both Alleles
- This will allow World to display the genotype of each flower
- Load World by clicking on the Red flowers
- Make sure both alleles for the flowers are showing
- User can confirm this by seeing little red/white rectangles in the upper left corner of each flower
- Set all colors to have Fitness to 5
- Calculate the allele frequencies using table provided in results
- Calculate genotype frequencies expected
- Run one generation only
^The results portion is combined with the answers to the questions portion of this assignment.

My homework partner for this week was Naomi Tesfaiohannes. She assisted in organization/structure of the notebook. Also, we discussed about evolution and why the results are the way they are.
