Activity 20.2 Quiz
Suppose the simulation is set to a moth population consisting of 10% black and 90% light gray individuals, and the environmental background undergoes a change from light gray to very dark gray. Which initial outcome do you predict will occur?

Activity 20.2 Quiz
Suppose that within a particular moth species, male moths are brightly colored and female moths have a dull coloration. Suppose also that the bright coloration of the males makes them more successful in attracting female mates. Which outcome of this simulation would you predict if the females matched the background well and the males matched the background poorly?
A.
B.
C.
D.
