D ≈ 0.49 A population of butterflies comes in three color morphs; orange (A1A1), black (A2A2), or orange with black spots (A1A2). You find that the frequency of orange butterflies is 0.49, and the frequency of black butterflies is 0.36. You do not know if the population is currently in HWE. What would you expect the frequency of spotted butterflies to be, if the population is under Hardy-Weinberg equilibrium? A ≈ 0.42 B ≈ 0.15 C ≈ 0.84 D ≈ 0.49 B. Migration is low and the populat...
