ANSWER

0.150.15. 0.35−0.20=0.150.35 - 0.20 = 0.15 shows the change between generations.

Practice questions

1 of 50Practice questions for this set
A population of wildflowers in the same meadow has two flower colors: purple and white. Scientists recorded trait frequency over 5 generations. Evolutionary change can be measured by shifts in trait frequency across generations. Data (out of 100 plants each generation):
  • Gen 1: 10 white, 90 purple
  • Gen 2: 20 white, 80 purple
  • Gen 3: 30 white, 70 purple
  • Gen 4: 40 white, 60 purple
  • Gen 5: 50 white, 50 purple
Which explanation best measures evolutionary change using proportional reasoning and the evidence?
