Data Table - Enter your Baby Bug Counts

Percentage Tables - Enter the Baby Bug percentages

Tip: Baby Bug Percentage = 100%  (Baby Bug Count) / (Total Number of Baby Bugs)

Tip: Blue Rimmed Baby Bug Percentage = BB Baby Bug Percent + Bb Baby Bug Percent

Observations and Questions

[1] Complete the Punnett square below when the parents are BB and bb.

[2] Describe your baby bug results from this data run in terms of genotypes and phenotypes.

[3] Why are there no BB baby bugs or bb baby bugs from this data run?

[4] Do the results for the allele distributions confirm the entries in your Punnett Square? Please explain.

[5] What evidence from this data run supports the hypothesis that the B allele is heterozygous dominant? Explain your reasoning.

Data Table - Enter your Baby Bug Counts from each data run

Data Averages Table - Enter your average Baby Bug Counts

Tip: BB Baby Bug Count Average = Sum of BB Baby Bug Counts / Number of Data Runs

Percentage Tables - Enter the Baby Bug percentages

Tip: Baby Bug Percent = 100%  (Baby Bug Count Average) / (Total Number of Baby Bugs)

Tip: Blue Rimmed Baby Bug Percentage = BB Baby Bug Percent + Bb Baby Bug Percent

Observations and Questions

[6] Complete the Punnett square below when the parents are BB and Bb.

[7] Using your Punnett Square, calculate the expected percentage of Blue Rimmed Baby Bugs and Yellow Rimmed Baby Bugs. Show your work. How do your percentage table results compare with the Punnett Square calculations? (higher, lower, similar) Explain your answer.

[8] Why do we use multiple data runs for this procedure? Explain your answer.

[9] For this set of parents, is it possible to draw conclusions about the genotype counts from examining the phenotypes? Why or why not? Use counts from one of your BB vs Bb data runs as part of your discussion.

Observations and Questions

[16] Describe the bug population change results during this data run in terms of genotypes and phenotypes.

[17] Do your results suggest anything about what the composition of this population might be at some distant point in the future? Defend your answer.

[18] Based on the initial starting population, use the Hardy-Weinberg equation to predict the future bug population phenotype composition. Hint: Under the Background tab, go to the Summary of Formulas Needed for Calculations section, see the example titled Using the Hardy-Weinberg Equation, then do Step 1 and Step 2 using the initial starting population for this data run.

[19] Is this population consistent with the expectations of the Hardy-Weinberg model, that is, is this population stable? Hint: Under the Background tab, go to the Summary of Formulas Needed for Calculations section, see the example titled Using the Hardy-Weinberg Equation, then do Step 3 and Step 4 for this data run.

Note: The topic below depends on sharing and comparing Procedure II - Part C data with your fellow classmates. Your instructor will inform you about the sharing process including details about how, where, and when, you should post your results and answers to the questions presented below.

[26] Compare your data run results to the results of the class as a whole. What population changes are possible? Are there any cases of extreme changes in population composition (e.g. all blue-rimmed or all yellow-rimmed)? What does the variety of population outcomes tell us about potential outcomes for small isolated populations that experience genetic drift?
