Question

# 1.the Punnett square below when the parents are female is BB and male is

bb.

Question:  Why are there no BB baby bugs or bb baby bugs from this data run?

2. the Punnett square below when the parents are female is bb and male is Bb.

Question: Using Punnett Square, calculate the expected percentage of Blue Rimmed Baby Bugs and Yellow Rimmed Baby Bugs. How percentage table results compare with the Punnett Square calculations? (higher, lower, similar) Explain your answer.

BB bug count:18   Bb bug count :1   bb bug count: 1

BB bug percentage: 90     Bb bug percentage: 5     bb bug percentage: 5

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

blue rimmed bug percentage: 95     Yellow rimmed bug percentage: 5

Question:

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

Question:

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

Question:

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.

Question:

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.
