whereas evolution in partially resistant plants originates from more complex dynamics
involving mutation , selection , and drift .
In this system , viral evolution in fully susceptible plants results from an equilibrium between mutation and genetic drift , whereas evolution in partially resistant plants originates from more complex dynamics involving mutation , selection , and drift .
