16. Suppose you have a population of 300 butterflies. If the population experiences a net growth of 12% in the following year, how many butterflies do you have? 17. Now suppose you have 300 eggs, but only 70% of those eggs become caterpillars, and only 80% of the caterpillars become adult butterflies. How many butterflies do you have? (For simplicity, assume that all butterflies survive to the next year in this example.) 18. Suppose you have a population of 150 butterflies, but a wildfire devastates the population and only 24 butterflies survive. What percent does the colony decrease by? © eScience Labs, 2018 Population Genetics
EXPERIMENT 3: STOCHASTIC EVENTS Post-Lab Questions 1. What observations can you make regarding the gene pool and gene frequency of the founding individuals? 19. Do these results vary between beakers #1 and #2? Why or why not? 20. What observations can you make about the genetic variation between the parent and founding populations? How does the source of the founding population (Beaker 1 or Beaker 2) influence these results? 21. How will future generations from Beaker 3 differ from those of their parent populations? © eScience Labs, 2018 Population Genetics
EXPERIMENT 4: NATURAL SELECTION Experimental Results Distribution of colors after Step 6: a. Blue: b. Red: Do you observe a selective advantage for the red or blue beads? Why?
