Using your Punnett Square, calculate the expected percentage of Blue Rimmed Baby Bugs and Yellow Rimmed Baby Bugs. How do your percentage table results compare with the Punnett Square calculations? Explain.
For Bb vs Bb parents, discuss how the genotype counts confirm the counts for the phenotypes in the display. Be specific. Use counts from one of your Bb vs Bb data runs as part of your discussion.

1. Describe the bug population change results during this data run in terms of genotypes and phenotypes.
2. Do your results suggest anything about what the composition of this population might be at some distant point in the future? Defend your answer.
3. Based on the initial starting population, use the Hardy-Weinberg equation to predict the future bug population phenotype composition.
